Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

Scientists built a quantum gate linking four-state photons, showing complex quantum tasks can be done with fewer steps using qudits.

D-Wave Quantum (NYSE:QBTS) has acquired Quantum Circuits, adding superconducting gate model technology to its existing quantum portfolio. The company has also joined the Southeastern Quantum ...

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.

Researchers developed compilation-based quantum process tomography, a framework that reconstructs quantum operations using fewer measurements than conventional methods.

AUSTIN, Texas, March 2, 2026 /PRNewswire/ -- The Advanced Quantum Technologies Institute (AQTI) today highlighted newly ...

Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic ...

In a laboratory at Oxford University, scientists have achieved something that once seemed science fiction: they made two separate quantum computers work together as one. Instead of being connected by ...

The truth is that even the most optimistic vendor estimates for this would put very nascent stages of enterprise value toward ...

Two promising pure-play quantum computer companies to consider are D-Wave Quantum (NYSE: QBTS) and IonQ (NYSE: IONQ). The ...

Oracle-based quantum algorithms cannot use deep loops because quantum states exist only as mathematical amplitudes in Hilbert space with no physical substrate. Criticall ...

Rigetti has achieved a significant error rate reduction with a 36-qubit system. This could pave the way for quantum computers with more qubits that can be used for AI ...
