A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum ...

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 ...

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 ...

Quantum computing holds the promise of transforming our information processing methodologies, and at its core, reliable quantum logic gates play an essential role in quantum information processing.

Army Researchers and Dr. Mikkel Heuck and Prof. Dirk Englund of the Massachusetts Institute of Technology have demonstrated the feasibility of a quantum logic gate comprised of photonic circuits and ...

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Subscribe to our newsletter ...

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 ...
