High-fidelity quantum logic gates applied to quantum bits (qubits) are the basic building blocks of programmable quantum circuits. Researchers at the Advanced Quantum Testbed (AQT) at Lawrence ...

Researchers at ETH Zurich have realized particularly stable quantum logical operations with qubits made of neutral atoms.

Quantum exchange or swap gates are an important part of quantum computers with a large number of qubits. Researchers at ETH Zurich have developed a swap gate for qubits made of neutral atoms that is ...

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...

The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the implementation of quantum logic gates. These are essentially operations that ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

ADELPHI, Md. -- Army researchers predict quantum computer circuits that will no longer need extremely cold temperatures to function could become a reality after about a decade. For years, solid-state ...
