“An Automata-Based Framework for Verification and Bug Hunting in Quantum Circuits” by Lengál et al., applies techniques ...

The research introduces an industry-first approach using ultrafast state-dependent kicks (SDKs) from nanosecond laser pulses, expected to enable quantum logic gates to operate at much faster ...

Unlike classical processors, quantum processors use quantum logic gates (or quantum gates) to manipulate qubits and perform calculations. Quantum gates are inherently different from binary logic ...

In the lucky circumstance that the totem FET source pins are connected to positive and negative rails that match the logic levels, a simple direct connection (a wire) will suffice. All that’s needed ...

reliable quantum logic gates play an essential role in quantum information processing. While various types of quantum gates have been demonstrated, photonic quantum gates are naturally compatible ...

A quantum gate is a physical process or circuit that changes the state of a qubit or a collection of qubits. In the quantum-computing context, if particles or superconducting qubits are the ...

The approach relies on using lasers to elicit ultra-fast bursts of electricity and has been used to create the fastest-ever logic gate—the fundamental building block of all computers. So-called ...

Currently we measure processing speeds in Gigahertz (GHz), but these new logic gates function on the scale of Petahertz (PHz). Previous studies have set that as the absolute quantum limit of how ...

D-Wave Systems revealed their next-generation quantum computing ... a fully functional gate-model QPU will consist of many task-specific architectural components, including modules for state ...
