Ballistic graphene Josephson junctions enter microwave circuits

Superconducting quantum microwave circuits can function as qubits, the building blocks of a future quantum computer. A critical component of these circuits, the Josephson junction, is typically made using aluminium oxide. Researchers ...

Superconducting metamaterial traps quantum light

Conventional computers store information in a bit, a fundamental unit of logic that can take a value of 0 or 1. Quantum computers rely on quantum bits, also known as a "qubits," as their fundamental building blocks. Bits ...

A new way to count qubits

Researchers at Syracuse University, working with collaborators at the University of Wisconsin (UW)-Madison, have developed a new technique for measuring the state of quantum bits, or qubits, in a quantum computer.

Explainer: The US push to boost 'quantum computing'

A race by U.S. tech companies to build a new generation of powerful "quantum computers" could get a $1.3 billion boost from Congress, fueled in part by lawmakers' fear of growing competition from China.

Researchers prevent the disappearance of quantum information

The properties of quantum mechanics could be used in technology and encrypting messages, but the disadvantage is the occasional disappearance of information. For the first time, a research group consisting of Finnish and ...

Researchers 'teleport' a quantum gate

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the "teleportation" of a quantum gate between two qubits, on demand.
