Trapped Ion Quantum Computer

The UK government has ploughed an extra £121m into quantum to drive development of the technology

Quantum computers are here. But could we ever build a quantum laptop?

Quantum computing systems have the potential to outperform classical computers on some tasks, helping to solve complex real-world problems in shorter times. Research teams worldwide have thus been trying to realize this quantum advantage over traditional computers, by creating and testing different quantum systems.

Quasi-periodic kicks result in very periodic qubits, thanks to donuts.

Researchers have achieved a key milestone toward the development of a fault-tolerant quantum computer. They were able to demonstrate a two-qubit gate fidelity of 99.5 percent -- higher than the 99 percent considered to be the threshold for building fault-tolerant computers -- using electron spin qubits in silicon, which are promising for large-scale quantum computers as the nanofabrication technology for building…

The race to scale quantum-computing hardware gains another option.

Microsoft has made progress with topological qubits, but they're still far from a full-scale quantum computer.

MIT senior Olivia Rosenstein's cross-country participation provides momentum to her studies as an experimental physicist working with 2D materials, optics, and computational cosmology.

Atom Computing has created the first quantum computer to surpass 1000 qubits, which could improve the accuracy of the machines

Sandia National Laboratories has produced its first lot of a new world-class ion trap, a central component for certain quantum computers. The new device, dubbed the Enchilada Trap, enables scientists to build more powerful machines to advance the experimental but potentially revolutionary field of quantum computing.

Sandia delivers its first devices that can hold 200 trapped ion qubits. The trap enables scientists to build more powerful machines to advance quantum computing.

IonQ Named As One Of TIME's 100 Most Influential Companies

The best quantum computers in the world are not powerful enough to hack bitcoin.

Physicists from the University of Amsterdam have proposed a new architecture for a scalable quantum computer. Making use of the collective motion of the constituent particles, they were able to construct new building blocks for quantum computing that pose fewer technical difficulties than current state-of-the art methods. The results were recently published in Physical Review Letters.

Researchers from RIKEN and QuTech—a collaboration between TU Delft and the Netherlands Organisation for Applied Scientific Research (TNO)— have achieved a key milestone toward the development of a fault-tolerant quantum computer. They were able to demonstrate a two-qubit gate fidelity of 99.5 percent—higher than the 99 percent considered to be the threshold for building fault-tolerant computers—using electron spin…

A 56-qubit trapped ion quantum computer from Quantinuum has demonstrated quantum supremacy as a random number generator

Japan's Fugaku supercomputer has gained an edge following the installation of the Reimei quantum computer.

Quantum physicists have developed an algorithm that uses a single qubit to solve a problem that had previously needed thousands of them.

MIT PhD student Alex Greene studies superconducting quantum computing systems, working to reduce errors that limit the length and complexity of the "programs" the computers can run.

By turning to a task unachievable by classical computers, scientists pin down a quantum revolution timeline.
