Aalto University physicists in Finland have set a new benchmark in quantum computing by achieving a record-breaking millisecond coherence in a transmon qubit — nearly doubling prior limits. This ...
Just as the sound of a guitar depends on its strings and the materials used for its body, the performance of a quantum computer depends on the composition of its building blocks. Arguably the most ...
Quantum computers are rapidly evolving from experimental settings towards commercially developed systems with ever-increasing numbers of qubits 1. Several important milestones have recently been ...
A Princeton team built a new tantalum-silicon qubit that survives for over a millisecond, far surpassing today’s best devices. The design tackles surface defects and substrate losses that have limited ...
On July 8, 2025, physicists from Aalto University in Finland published a transmon qubit coherence measurement in Nature Communications that dramatically surpasses previous scientifically published ...
TOKYO--(BUSINESS WIRE)--Toshiba Corporation (Toshiba) has confirmed a breakthrough technology that promises to advance progress toward the development of higher-performance quantum computers through ...
Researchers at Toshiba Corporation (TOKYO: 6502) have achieved a breakthrough in quantum computer architecture: the basic design for a double-transmon coupler that will improve the speed and accuracy ...
Quantum computing promises to solve complex problems exponentially faster than a classical computer, by using the principles of quantum mechanics to encode and manipulate information in quantum bits ...
For this study, we used high-resistivity silicon substrates (10,000 Ω cm). Prior to the base layer deposition, the substrate is cleaned in a Piranha solution at 80 °C, followed by dipping in ...
