[IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an old part, it won’t work at very high frequencies, but the circuit is ...

In classical computing, this is similar to the function of an XOR gate, but in the quantum environment, it allows qubits to exist in a superposition of states, enabling the simultaneous processing ...

Purdue University researchers are among the first to build a gate – what could be a quantum version of a transistor, used in today’s computers for processing information – with qudits. Whereas qubits ...

What is new is the deterministic (eg, once entanglement is established, the teleportation always succeeds) and repeatable teleportation of a quantum logic gate. "Previous demonstrations of quantum ...

Those qubits will be the key part of quantum computing if they can be effectively controlled. The Oxford researchers had already used that technology to create logic gates that were far more ...

Researchers at QuTech, in collaboration with Fujitsu and Element Six, have demonstrated a complete set of quantum gates with error probabilities below 0.1%. While ...

[Related: In photos: Journey to the center of a quantum computer] Here are the requirements for the problem: The computer needs to find the most optimal gates to assign incoming and connecting ...
