Oxford Ionics, a world leader in trapped-ion quantum computing, today announced its co-founder and CEO, Chris Ballance, will be speaking at WebSummit this week in Lisbon, Portugal.

IonQ, a leader in the quantum computing industry, announced today a partnership with NKT Photonics, a subsidiary of Hamamatsu Photonics, to procure next-generation laser systems for IonQ’s trapped-ion quantum computers and networking equipment. The partnership involves NKT Photonics developing and delivering three prototype optical subsystems to IonQ in 2025, designed to support the commercialization of IonQ’s data center-ready quantum computers – such as IonQ Tempo and future barium-based systems.

Supersolids are a new form of quantum matter that has only recently been demonstrated. The state of matter can be produced artificially in ultracold, dipolar quantum gases. A team led by Innsbruck physicist Francesca Ferlaino has now demonstrated a missing hallmark of superfluidity, namely the existence of quantized vortices as system’s response to rotation. They have observed tiny quantum vortices in the supersolid, which also behave differently than previously assumed.

IonQ, a leader in the quantum computing industry, announced today that it is developing photonic integrated circuits (PICs) and chip-scale ion trap technology for trapped ion quantum computing in partnership with imec, a world-renowned R&D center in nanoelectronics and digital technologies. By optimizing the design, production, and integration of chip-scale photonic devices and ion traps for scalable and high-performance quantum computers, the developments aim to push the boundaries of quantum computing performance.

IonQ, a leader in the quantum computing industry, today announced financial results for the quarter ended September 30, 2024.

Universal Quantum, a leader in scalable quantum computing, has achieved a major research breakthrough in fault-tolerant quantum computation with “Constant-Time Magic State Distillation”. This research advancement is poised to make large-scale quantum computation significantly faster and more feasible. By reducing the time and physical resources required to produce high-fidelity qubits, Universal Quantum’s discovery will transform how quantum computers handle error correction, directly impacting practical implementations in the field.

A team of physicists led by Johannes Zeiher, research group leader in Immanuel Bloch's Quantum Many-Body Systems department and co-founder of the MPQ spin-off planqc, has achieved significant progress in scaling up quantum computing platforms with neutral atoms.

University of Waterloo researchers have successfully demonstrated the ability to measure and reset a trapped ion qubit to a known state without disturbing neighbouring qubits just a few micrometres away — a distance smaller than the width of a human hair, which is about 100 micrometres thick.

In the CiRQus project, we have implemented laser-controlled interactions between a highly-excited circular Rydberg qubit and a second ionic core electron. This achievement advances control of circular Rydberg atoms from the microwave to the optical domain by combining established tools for manipulating trapped ions with neutral atom arrays.

In work published in Science Advances, Hayato Goto from the RIKEN Center for Quantum Computing in Japan has proposed a new quantum error correction approach using what he calls “many-hypercube codes.” This approach, which turns out to have an elegant geometry, could help realize extremely efficient error corrections and contribute to highly parallel methods that will allow fault-tolerant quantum computing, the next stage in the evolution of quantum computers.
