Shrinking qubits for quantum computing with atom-thin materials

For quantum computers to surpass their classical counterparts in speed and capacity, their qubits—which are superconducting circuits that can exist in an infinite combination of binary states—need to be on the same wavelength. ...

Quantum circuit black hole lasers to explore Hawking radiation

The fundamental forces of physics govern the matter comprising the universe, yet exactly how these forces work together is still not fully understood. The existence of Hawking radiation—the particle emission from near black ...

Researchers in Sweden develop light emitter for quantum circuits

The promise of a quantum internet depends on the complexities of harnessing light to transmit quantum information over fiber optic networks. A potential step forward was reported today by researchers in Sweden who developed ...

A benchmark for single-electron circuits

Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, ...

Bringing a power tool from math into quantum computing

The Fourier transform is an important mathematical tool that decomposes a function or dataset into a its constituent frequencies, much like one could decompose a musical chord into a combination of its notes. It is used across ...
