By Kacy Mixon, M.S., LMFT[Flickr, Forgiveness ! by Craig Sunter, CC BY-ND 2.0] Retrieved on September 17, 2015As discussed in our previous post, military couples are particularly vulnerable to infidelity. Infidelity is considered one of the most difficult issues to treat in couples’ therapy . For military couples, though, treatment can be even more difficult  depending on the availability of each partner to come to therapy. For instance, if partners are separated geographically, it may be difficult to coordinate professionals or technological resources to implement treatment before the problem completely dismantles the relationship. Confidentiality can also be problematic when treating military couples because infidelity is considered a punishable offense under the Uniform Code of Military Justice (UCMJ-Article 134). Service members suffering from a decline in emotional expressiveness and regulation often associated with post-traumatic stress disorder may also complicate treatment. The broad range of negative impacts that infidelity imposes on military couples as well as increased vulnerability to this problem suggests a need for treatments tailored to military couples.One evidence-based treatment approach designed specifically for military couples struggling with infidelity has been shown to produce effective outcomes . The theoretical foundation under girding this approach draws on interventions focusing on trauma and forgiveness. This treatment model guides couples through three stages: 1) Impact stage, 2) Meaning Stage, and 3) Moving on stage. The table below provides more detailed tasks that therapists utilizing this approach aim to achieve with clients in therapy.Snyder, K., Gasbarrini, M., Doss, B. & Scheider, D. (2011). Intervening with military couples strugling with issues of sexual infidelity. Journal of Contemporary Psychotherapy, 41, 201-208.This infidelity-specific treatment model was developed by Kristina Coop Gordon, Donald H. Baucom, and Douglas K. Snyder. Empirical evidence surrounding the treatment approach demonstrates effectiveness. In one study, couples demonstrated significantly less post-traumatic stress symptoms, depression and marital distress. Furthermore, there was greater forgiveness for the person who engaged in the affair upon completing treatment . This treatment approach has also been used by Army chaplains tailoring it to military couple needs and has shown promising results . More information on this therapy approach can be found in the book titled Helping Couples Get Past the Affair: A Clinician’s Guide.References  Snyder, D.K., Gasbarrini, M.F., Doss, B.D., & Scheider, D.M.

NEW DELHI: The water level of Yamuna is receding and the river is now flowing below the danger mark of 205.33 metres, an official said on Thursday.”The level of Yamuna at railway bridge was 206.60 metres at 10 am. It is expected to recede further,” the official at the flood department’s control room said. The water level of Yamuna reached the highest level of 206.60 metres Wednesday morning and remained constant for nearly seven hours. The river started receding from afternoon and flowed at 206.44 metres at 6 pm.

Officials said around 23,000 affected people were evacuated from the flood-plains to safer places. Over 18,000 of them were accommodated in more than 2700 relief tents set up by the Delhi government agencies. A total of 35 boats were deployed to rescue the stranded people. Chief Minister Arvind Kejriwal said that he was in touch with the Haryana government and expected that the situation will improve by Thursday as the neighbouring state was reducing the amount of water being released towards Delhi.

A Northern Railway spokesperson said rail traffic over the old Yamuna bridge, temporarily suspended on Tuesday night, was restored at 4.25 pm on Wednesday with speed restriction of 20 kmph. On Wednesday afternoon, the Chief Minister met the people who were shifted from inundated low-lying areas to relief tents near Usmanpur and assured them of all the help. “Met the flood affected people at the Yamuna bank. Most people have left their belongings in their houses but its good thing that there is no loss of life. Arrangements of tents, food, water and medicine have been made. Let us know if there is any shortage, we will immediately do the needful,” CM Kejriwal tweeted in Hindi after the visit.
Prof. Susan Coppersmith and Prof. Mark Eriksson discuss the paper they and their co-authors published in Proceedings of the National Academy of Sciences with Phys.org, noting that overall goal of the research program is to develop quantum bits for a quantum computer using technology that is similar to that used for current classical computers. “The advantages of this strategy arise for two main reasons.” Coppersmith tells Phys.org. “First, enormous investments have been made to develop large-scale classical electronics, and one hopes that this investment can be leveraged to facilitate scale-up of quantum electronics. Second, the similarity in technology facilitates integration of quantum and classical processors.” Integration is important, Eriksson adds, because a large-scale classical computer will almost certainly be necessary to control the operation of a quantum computer.An early step towards this goal is to fabricate high-fidelity individual qubits. This paper focuses on the so-called singlet-triplet qubit, which was first fabricated in gallium arsenide (GaAs) devices. “The operation of a singlet-triplet qubit in GaAs is complicated by strong coupling between the electron spins and nuclear spins, Eriksson explains. “Silicon has much weaker coupling between the electron spins and nuclear spins, and most of the nuclei in silicon have spin zero, so the electron spins in silicon can stay coherent much longer than in GaAs.” In fact, measurements of a singlet-triplet qubit in natural silicon indeed yield much longer coherence times than in GaAs, but because the qubit operations themselves rely on having a magnetic field difference between the dots – a difference that also arises from the nuclei themselves – the qubit operations in that work were much slower than in GaAs. “Our work shows that using an integrated micromagnet enables faster gate operations by imposing a larger magnetic field difference between the quantum dots,” Coppersmith points out, “and it does so without introducing measurable additional decoherence, which improves the overall performance of the qubit.” Explore further Electrical control of nuclear spin qubits Citation: Quantum meets classical: Qubit fabricated with integrated micromagnet increases speed of quantum manipulation in silicon (2014, August 25) retrieved 18 August 2019 from https://phys.org/news/2014-08-quantum-classical-qubit-fabricated-micromagnet.html Specifically, the paper states that the integrated micromagnet provides a promising path toward fast manipulation in materials with small concentrations of nuclear spins, including both natural silicon (Si) and isotopically enriched 28Si. “Nuclear spins in GaAs and other materials, such as InSb (Indium Antimonide), reduce qubit coherence – but this strong coupling also enables fast manipulation,” Eriksson tells Phys.org. “However, if the decoherence effects are reduced by using a material with weaker coupling to nuclear spins, it’s necessary to find another way to create a large magnetic field difference between the quantum dots – and the integrated micromagnet enables this.” (Phys.org) —The ubiquitous classical digital computer encodes data in bits (a portmanteau of binary and digits) in either a 0 or 1 state. On the other hand, while a quantum computer also uses 0/1 data representation, these qubits (from quantum and bits), qubit states 0 and 1 can be simultaneously in what is known as a superposition – and a quantum computer can also make use of entanglement. For these reasons, quantum computers can potentially solve problems whose complexity is too resource-intensive for classical computation. That being said, quantum computers are very difficult to construct. Recently, however, scientists at University of Wisconsin, Madison have fabricated a qubit in a silicon double-quantum dot in which the qubit basis states are the singlet state and the spin-zero triplet state of two electrons. (A double quantum dot links two quantum dots – semiconductor nanostructures that confine the motion of conduction band electrons, valence band holes, or excitons in all three spatial directions.) Moreover, the researchers have for the first time integrated a proximal micromagnet, allowing them to create a large local magnetic field difference between the two sides of the quantum dot – thereby greatly increasing their ability to manipulate the qubit without injecting noise that would induce superposition decoherence. Journal information: Proceedings of the National Academy of Sciences “One big challenge was fabricating a suitable device, that being a double quantum dot in which a micromagnet is incorporated,” Coppersmith continues. Devices with incorporated micromagnets had previously been investigated in GaAs in a slightly different context, but the fabrication procedure in the University of Wisconsin devices differs from that used in the GaAs devices, requiring novel processes to be developed. “A further challenge arose because the micromagnetic field was somewhat different than what was expected based on measurements of cobalt films and our numerical calculations,” notes Eriksson. “Therefore, to perform the experiments we had to use the properties of the qubit itself to figure out what the actual fields on the quantum dots were.” By so doing, the researchers found that the field from the micromagnet depended on the applied uniform field, which enabled them to investigate the qubit properties for two magnitudes of the micromagnet field.Interestingly, the paper states that the scientists’ fabrication techniques being similar for both quantum dot-based qubits and donor-based qubits in semiconductors suggests that micromagnets should also be applicable to donor-based spin qubits. “The micromagnet in the device that we measured is created by depositing the metal cobalt by Electron Beam Physical Vapor Deposition (EBPVD), onto the top of the sample,” Coppersmith says. “Therefore, applying the technique to other semiconducting qubit architectures in which the qubits are defined by evaporated metal top gates is rather straightforward.” (EBPVD uses an electron beam to bombard a target and convert some of its atoms into a gas, which then precipitate and coat all surfaces in the vacuum chamber.) In practice, however, some of the gates on these devices will be made of non-magnetic materials – typically aluminum or gold –resulting in a small number of cobalt gates.The researchers also describe the unique characteristics of a large-scale quantum computer based on their approach: Once high-quality single qubits and two-qubit gates are achieved, then because the technology is close to that already used in classical electronics and the qubit size (< 1µ) is small, scaling up to devices with large numbers of qubits could be feasible. This plausible path to large numbers of qubits has sparked significant interest in electrically-gated qubits in semiconductors."The next steps in our research are to increase both the magnitude of the field difference between the quantum dots, and the number of qubits by increasing the number of quantum dots," Coppersmith tells Phys.org. "Both steps are being implemented in new devices that have been designed and are currently being fabricated. We're also working on other qubit implementations in silicon quantum dots1,2, all of which use electrical initialization, manipulation and readout, and therefore have the potential advantages of integrability and scalability." Moreover, Eriksson points out that being able to control local magnetic fields in a nanoelectronic device could be very useful for spintronics.

An optical image of a complete device showing the micromagnet is included in SI Appendix. Gates labeled left side (LS) and right side (RS) are used for fast pulsing. The curved arrow shows the current path through the QPC used as a charge sensor. (B) IQPC measured as a function of VLP and VRP yields the double-dot charge stability diagram. Electron numbers in the left and right dot are indicated on the diagram. The red arrow denotes the direction in gate voltage space Vε = √(ΔV2LP +ΔV2RP) that changes the detuning ε between the quantum dots. (C) Schematic energy diagram near the (0, 2) to (1, 1) charge transition, showing energies of singlet S and triplet T states as functions of ε. The exchange energy splitting J between S and T0, the Zeeman splitting EZ between T− and T0, and the tunnel coupling tc are also shown. At large ε, in the presence of a field difference between the two dots, S and T0 mix, and the corresponding energy eigenstates are |↑↓〉 and |↓↑〉. At small ε, the small transverse field from the micromagnet and the nuclear fields turns the S-T− crossing into an anticrossing (zoom in). Pulsing through this anticrossing with intermediate velocity transforms S into a superposition of S and T−, leading to Landau–Stückelberg–Zener oscillations at the frequency corresponding to the S-T− energy difference (22). The pulse used to observe the spin funnel and S-T− oscillations shown in E is also shown, where the pulse voltage VP is applied along the detuning axis.

(E) Spin funnel (2) measurement of the location of the S-T− anticrossing as a function of external magnetic field Bext and Vε. The data were acquired by sweeping along the detuning direction with the pulse on, with the vertical axis reporting the value of the detuning at the base of the pulse. The spin funnel occurs when S-T− mixing is fast, which locates the relevant anticrossing. (F and G) S-T− oscillations acquired at different external B fields. The oscillation frequency increases with increasing Bext.
