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 ...

The Case for IonQ Stock. IonQ has established itself as a leader in gate-based quantum computing, with its trapped-ion technology showing promising results for general-purpose quantum applications.

The quantum computing industry has emerged as one of 2024's hottest investing themes, with leading players seeing their stocks surge amid growing commercial and government interest. Industry ...

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 ...

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