Researchers have demonstrated that a strange type of quantum particle called the anyon, believed to exist in only two dimensions, can also be created in one dimension. Further studies exploring different types of one-dimensional anyons could bring scientists one step closer to using the particles as a fundamental unit of memory in a quantum computer.

Floquet engineering, in which the properties of the system are qualitatively modified by strong periodic driving, provides a route to realizing new kinds of quantum systems. However, a Floquet-engineered Hamiltonian is always accompanied by unwanted heating.

His answers included recommending resources for learning more about quantum computing, to highlighting current and future endeavors involving quantum cryptography.

RQS senior investigator Nicole Yunger Halpern is part of a team that’s developed a new technique that can reset qubits in quantum computers highly effectively, a critical task for successful quantum computing.

Scientists seeking better methods for controlling the quantum interactions between light and matter demonstrated a novel way to use light to give electrons a spinning kick. In the journal Nature Photonics, they reported the results of an experiment, showing that a light beam can reliably transfer orbital angular momentum to itinerant electrons in graphene.

Researchers at RQS and Harvard University repurposed superconducting qubit technology to detect exotic forms of superconductivity, revealing delicate spin-triplet electron pairings and opening new opportunities for condensed matter physics and quantum computing.

The established knowledge and technical infrastructure from decades of quantum research are allowing researchers to harness quantum technologies in unexpected, innovative ways and creating new research opportunities. In a paper published in the journal Nature Physics, a collaboration between theorists at JQI and experimentalists at Harvard University presented a technique that repurposes the technology of superconducting circuits to study samples with exotic forms of superconductivity. The collaboration demonstrated that by building samples of interest into a superconducting circuit they could spy on exotic superconducting behaviors that have eluded existing measurement techniques.

We have written a review article describing advances in chip-integrated laser technologies in the visible and short near-infrared wavelength regimes.

Researchers at the University of Maryland are exploring the use of superconducting junctions to advance new qubit designs for quantum simulations.

Quantum computers are the basis of a growing industry. However, their technology isn’t standardized yet, and researchers are still studying the physics that goes into quantum devices. Even the most basic building blocks of a quantum computer—qubits—are still an active research topic. In an article in the journal Physical Review A, JQI researchers proposed a way to use the physics of superconducting junctions to let each function as more than one qubit.
