Scientists set quantum speed limit


Quantum speed limit time of topological qubits influenced by

Quantum theory sets a bound on the minimum time required to transform from an initial state to a target state. The bound is known as quantum speed limit ...

Quantum speed limits - Quantum Thermodynamics - UMBC

The apparent contradiction quickly dissolves, once one realizes that in the lingo of computer science a “speed-up” simply refers to a smaller number of required ...

Implementing two-qubit gates at the quantum speed limit - OSTI.GOV

The speed of elementary quantum gates, particularly two-qubit gates, ultimately sets the limit on the speed at which quantum circuits can ...

Speed Limit of Single Atom Trapped in Fabry-Perot Microresonator

A quantum speed limit (QSL) in quantum mechanics denotes the shortest amount of time required for a quantum system to transition between two ...

Quantum speed limit may put brakes on quantum computers

If an object in the quantum world travels from one location to another, researchers can't measure exactly when it has left nor when it will ...

Scientists Say Quality of Clocks Set Limits For Quantum Computers

The research team was able to show that since no clock has an infinite amount of energy available (or generates an infinite amount of entropy), ...
