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 ...

Two independent research teams have each demonstrated collisional quantum gates using fermionic atoms: a long-sought ...

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 ...

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.

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. But new in the way they share ...

Scientists at MPQ successfully process quantum information with a system comprising an optical photon and a trapped atom. When it comes to recognizing complex patterns or to decoding encrypted ...

Quantum computing represents a paradigm shift from classical computation by harnessing inherent quantum phenomena such as superposition and entanglement to perform operations beyond the scope of ...

Researchers have demonstrated the first three-qubit high-fidelity iToffoli native gate in a superconducting quantum information processor and in a single step. This demonstration adds a novel ...
