Quantum Logic Gates, Quantum Circuits The Toffoli or the controlled-controlled-NOT (CCNOT) is a key logical gate in classical computing because it is universal, so it can build all logic circuits ...

The V gate and V+ gate are quantum gates used to implement more complex logic. The operations of these two gates are similar to the AND and OR gates in classical computing. However, their ...

Quantum logic gates are formed by entangled networks of ... potentially correcting errors using quantum codes." Whereas the classical switches in your laptop or mobile phone can run for many ...

The realization of a full-scale quantum computer presents one of the most challenging problems facing modern science. Even implementing small-scale quantum algorithms requires a high level of ...

Quantum gates are similar to classical logic gates, but their operations extend beyond binary bit manipulations to include more complex transformations of qubits. In quantum computers, managing ...

Quantum gates perform operations on qubits, which are the quantum equivalent of classical computer bits; they are essential for constructing quantum algorithms and are the fundamental building ...

"This causes the excited atom—in the classical picture—to expand immensely ... More information: Thomas Stolz et al, Quantum-Logic Gate between Two Optical Photons with an Average Efficiency ...

The method used by D-Wave, called quantum annealing, can already compete against classical computers and start addressing realistic problems; on the other hand, gate-based quantum computers ...
