Error suppression opens pathway to universal quantum computing. A scientist at the University of Sydney has achieved what one quantum industry insider has described as…
A design for the photonic structure that traps two photons. Photons travel in the horizontal direction, one into each arm of the cross. The holes…
Linking multiple copies of these devices may lay the foundation for quantum computing. Once unimaginable, transistors consisting only of several-atom clusters or even single atoms…
In this illustration, two sheets of graphene are stacked together at a slightly offset “magic” angle, which can become either an insulator or superconductor. “We…
Constructing a small-scale circuit to further examine and explore the possibility. Credit: Tokyo University of Science The basic units of a quantum computer can be…
Scientists who study topological materials face a challenge — how to establish and maintain control of these unique quantum behaviors in a way that makes…

A group of scientists from the RIKEN Center for Emergent Matter Science in Japan have succeeded in taking repeated measurements of the spin of an…
Superconducting radio-frequency cavities, such as the one seen here, are used in particle accelerators. They can also solve one of the biggest problems facing the…
A sensor using quantum entanglement can determine if a single magnetic excitation is present in a millimeter-sized sphere. This moves us closer to the limit…
In a diamond crystal, three carbon atom nuclei (shown in blue) surround an empty spot called a nitrogen vacancy center, which behaves much like a…
Researchers from MIT, Google, and elsewhere have designed a novel method for verifying when quantum processors have accurately performed complex computations that classical computers can’t.…
Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a quantum chemistry simulation benchmark to evaluate the performance of quantum devices and…
Researchers at Princeton University have made an important step forward in the quest to build a quantum computer using silicon components, which are prized for…
A simulation of electrons at different energies scattering off atomic defects like those in samarium hexabroide. By observing such waves, the researchers measured the electron’s…
Google announced this fall to much fanfare that it had demonstrated “quantum supremacy” – that is, it performed a specific quantum computation far faster than…
