Bus Service for Qubits

Superconducting circuits speak directly with semiconductor-based qubits to push forward the technology needed for quantum computing.

Topological Superconductors

Theoretical physicists at the JQI have done an important step forward to understand qubits in a real-world setup. In a new study they show, for the first time, that qubits can successfully exist in a so called topological superconductor material even in the presence of impurities in the material and strong interactions among participating electrons.

Quantum Longitude

“Quantum weirdness,” a phrase related to the power and the un-intuitive nature of quantum reality, is expected to facilitate speeded-up computation -- quantum computing -- for performing certain specialized tasks, such as factoring numbers. A proposed scheme should be helpful in sustaining coherence by carefully making mid-calculation corrections.

The unit cell for “spin ice” materials consists of two tetrahedrons. The arrows show the orientation of the magnetic atoms within the material.

Freezing Magnetic Monopoles

Stephen Powell, a scientist at the JQI, has sharpened the theoretical framework under which magnetic monopoles (entities with isolated north or south magnetic poles) can operate.

Seeing the Light with NIST's New Noiseless Optical Amplifier

Scientists working at the JQI and NIST have demonstrated that they can amplify weak light signals without adding noise while also carrying more information—more pixels—than other low-noise amplifiers.

Disorderly Conduct in Quantum Coherence

A new experiment conducted at the JQI examines the relationship between quantum coherence, an important aspect of certain materials kept at low temperature, and the imperfections in those materials.

First Observation of the Hall Effect in a Bose-Einstein Condensate

NIST researchers have observed for the first time the Hall effect in a gas of ultracold atoms.

Short Movie Stored in An Atomic Memory

Scientists at the JQI have stored not one but two letters of the alphabet in a tiny cell filled with rubidium atoms which are tailored to absorb and later re-emit messages on demand.

A Magnetic Approach to Lattices

As an extension of their work on generating synthetic fields, Ian Spielman's group has developed a new kind of lattice for atoms.

Fast, Low-power All-optical Switch

An optical switch developed at the JQI spurs the prospective integration of photonics and electronics.
