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 ...

The quantum computing revolution draws ever nearer, but the need for a computer that makes correctable errors continues to ...

As a result, quantum computing investors should ensure that a single company doesn't make up more than a 1% position within a portfolio. That way, if it goes to $0, it won't have as significant an ...

“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 ...

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 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 computing is in its early stages, and two promising companies in the field are D-Wave and IonQ. D-Wave generated a jaw-dropping 509% year-over-year increase in first-quarter sales to $15 ...

This year, it plans to launch a new modular quantum computing system that links together four 9-qubit chips to create a 36-qubit system with a median gate fidelity of 99.5%.
