(PhysOrg.com) -- To build a quantum computer, it's essential to be able to quickly and efficiently manipulate the quantum states of qubits. The qubits, which are the basic unit of quantum information, can be composed of many ...
Canadian based D-Wave has announced on its blog that it has developed a new quantum computer for use by businesses. Called Advantage, the new system has 5,000 qubits and 15-way qubit connectivity. The new machine will be ...
Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions by leaking judiciously ...
