QuTech and Fujitsu have recently announced a partnership to develop a blueprint for a scalable quantum computer. This collaboration is centered around delivering a comprehensive framework for building quantum computers that addresses all major components required for scalability and reliability. According to the announcement, the partnership takes a “full-stack approach,” which encompasses everything from physical qubit modules to high-level error-correction algorithms designed to stabilize quantum computations.

Some phenomena that occur in materials can be challenging to mimic using quantum computers, leaving gaps in the problems that scientists have explored with quantum hardware. To fill one of these gaps, MIT researchers developed a technique to generate synthetic electromagnetic fields on superconducting quantum processors. The team demonstrated the technique on a processor comprising 16 qubits.

A research team led by Pacific Northwest National Laboratory (PNNL) scientists will use a combination of advanced electron microscopy, materials synthesis, and theoretical techniques to study quantum behavior in materials at the atomic level. They will use model material systems to study how electrons and their properties, such as spin and orbit, move through the materials. The project will focus on understanding transport phenomena, collectively known as Hall effects. Hall effects occur when an electric current flows through a material, typically in the presence of an external magnetic field, resulting in a build up of charge or spin in a direction perpendicular to the current flow.

Now, those researchers have determined why they were able to trounce the quantum computer at its own game. Their answer, presented on October 29 in Physical Review Letters, reveals that the quantum problem they tackled — involving a particular two-dimensional quantum system of flipping magnets — displays a behavior known as confinement. This behavior had previously been seen in quantum condensed matter physics only in one-dimensional systems.

Zero Point Cryogenics (ZPC) offers a practical and high-performing solution for low-temperature research with their newest product line: the Continuous Cold Cryostats. These systems are workhorses designed for continuous operation around 1 K, and optimized to meet the needs of labs requiring both cool-down, high cooling power, and rapid sample exchange, while maintaining the quality and reliability of all ZPC systems. The Continuous Cold systems are an ideal choice for researchers who don't require a dilution refrigerator's millikelvin temperature range but still desire an upgradable path and ease of use for sensitive experiments in fields like quantum technology and materials science.

Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir the exciton-polariton condensate, which emits the linearly polarized light with polarization axis following the stirring direction. The rotation of the linear polarization of the emitted light directly corresponds to the stirring of the polariton spin. The speed of such modulation in time can reach GHz range, thanks to ultrafast dynamics of the polariton system. Remarkably, the team found that this precession occurs only at a specific resonant condition of the external stirring and internal system parameters. The work has been published in Optica.

An old physical phenomenon known as the Hall effect has revealed some new tricks, according to a team co-led by researchers at Penn State and the Massachusetts Institute of Technology (MIT). They have reported their findings, which they said have potential implications for understanding the fundamental physics of quantum materials and developing applied technologies such as quantum communication and harvesting energy via radio frequencies in Nature Materials.

For the first time since the discovery of the material MnBi2Te4 (MBT), researchers at the University of Twente have successfully made it behave like a superconductor. This marks an important step in understanding MBT and is significant for future technologies, such as new methods of information processing and quantum computing.

A team of experimentalists working with cold Rydberg atoms have used Quantum magnetometry to help the atomic clocks and magnetometers used for precise time keeping in navigation, telecommunication and aviation, achieve higher precision and make them additionally robust.

A research team led by Prof. LIN Hao from the High Magnetic Field Laboratory at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with multiple international research teams, has successfully achieved an atomically controlled insulator-to-metal transition in iridate/manganate heterostructures.
