Dueling Technologies: Gate-Based Precision vs. Quantum Annealing Speed Rigetti is building universal, gate-based quantum computers using superconducting qubits, currently operating the 84-qubit ...

Quantum computing is in its early stages, and two promising companies in the field are D-Wave and IonQ. IonQ is constructing a quantum computer network, and to that end, has announced a $1 billion ...

Quantum computing is already big business, ... According to Rigetti, its superconducting qubits achieve ultra-fast gate speeds of 60 to 80 nanoseconds, ...

Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state Date: February 23, 2023 ...

Researchers have developed a new protocol for characterizing quantum gate errors, paving the way toward more reliable quantum simulations and fault-tolerant quantum computing.

“Quantum gate teleportation” – the construction of quantum gates whose output is conditional on the state of an input gate elsewhere – has therefore become an active field of research. Such gates have ...

Quantum computing is now within reach, thanks to a major breakthrough in which scientists demonstrate that a key building block of quantum computers, a quantum Fredkin gate, can be assembled.

Quantum computers, on the other hand, exploit the ability of quantum particles to be in two or more states at the same time. A quantum bit or “qubit” can therefore be “0” or “1” or any combination of ...
