Reducing Magnetic Fields to Combine Qubits With Superconductors to Advance Quantum Computing Development
Quantum Computing with Holes Scientists found a new and promising qubit at a place where there is nothing. Hole spin qubits in layered material. The two holes are confined to the germanium-rich layer just a few nanometers thick. On top, the electrical gates are formed by individual wires with voltages applied. The positively charged holes […]
Finding a Way to Encode Quantum Coherence in Photon Pair Pulses
Observing quantum coherence from photons scattered in free-space Quantum Coherence Observed CAS. Each optical pulse from the laser is sent through a phase Converter, which creates two coherent pulses, while the multi-mode Analyzer measures the signals scattered off the target surface, implemented with regular bright paper. A single-photon-detector-array is used as the detection device, with […]

New quantum repeaters could enable a scalable quantum Read More… + Quantum repeaters that can store multiplexed signals; provide heralded signals of entanglement; and operate at telecommunications wavelengths have been developed by two independent research teams. Their work could prove to be an important step towards the creation of a scalable quantum internet. Quantum repeaters […]
The Shorts | 6/15/21 | Science and Research in Quantum Computing
Physicists reveal how motion can be generated by frustration | Hanai and Littlewood encountered the concept of exceptional points as they were trying to understand the behavior of a type of quantum matter which can gain or lose energy. They had an inkling that they could explain it without the language of quantum mechanics. “We […]
Quantum Materials Focus of Ohio State Research
A quantum step to a heat switch with no moving parts The cones in this image illustrate the equations of motion of electrons when an external magnetic field is applied to the bismuth alloy engineered for the study. Green lines and purple lines represent electrons that generate and absorb energy, respectively. (Image Credit: Renee Ripley) […]
Researchers Create Easy-to-Use, Fits-in-a-Rack QKD System
Researchers Take Quantum Encryption Out of the Lab In a new study, researchers demonstrate an automated, easy-to-operate quantum key distribution (QKD) system using the fiber network in the city of Padua, Italy. The field test represents an important step toward implementing this highly secure quantum communication technology using the type of communication networks already in […]
Next-Gen Air Transportation Pilot Program to Study Quantum Computing, Urban Air Mobility
UAM vehicles and UAV flying urban areas. (Image Credit: Sumitomo Corporation) The Sumitomo Corporation is leading collaboration between OneSky Systems and Tohoku University to study the feasibility of applying quantum computing optimization algorithms to the concept of Urban Air Mobility, or UAM. UAM and quantum computing are two technologies on the edge of high-tech. To […]
Classical Systems, Quantum Systems, and Entanglement Demonstrate a Quantum Advantage
UArizona Engineers Demonstrate a Quantum Advantage Quantum computing and quantum sensing have the potential to be vastly more powerful than their classical counterparts. Not only could a fully realized quantum computer take just seconds to solve equations that would take a classical computer thousands of years, but it could have incalculable impacts on areas ranging […]
Rice University’s RAMBO, Spintronics Research May Advance Quantum Memory
Odd angles make for strong spin-spin coupling Rice physicists’ RAMBO reveals magnetic phenomenon useful for quantum simulation and sensing Sometimes things are a little out of whack, and it turns out to be exactly what you need. That was the case when orthoferrite crystals turned up at a Rice University laboratory slightly misaligned. Those crystals inadvertently […]
Following Individual Atoms, Real-Time, to Aid Quantum Material Development
Following atoms in real time could lead to better materials design Researchers have used a technique similar to MRI to follow the movement of individual atoms in real time as they cluster together to form two-dimensional materials, which are a single atomic layer thick. This technique isn’t a new one, but it’s never been used […]
