Nearly 20 quantum computing companies have been chosen to enter the initial stage of DARPA’s Quantum Benchmarking Initiative (QBI), in which they will characterize their unique concepts for creating a useful, fault-tolerant quantum computer within a decade.

MIT researchers developed a photon-shuttling “interconnect” that can facilitate remote entanglement, a key step toward a practical quantum computer.

Beginning in January 2025, users at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (Berkeley Lab) will be able to access IBM’s quantum computers over the cloud for their research, allowing users to take advantage of these next-generation systems for certain scientific applications.

Qilimanjaro Quantum Tech, in partnership with Do IT Now, is proud to announce the signature of the procurement contract of EuroQCS-Spain quantum computer for EuroHPC Joint Undertaking. Under this agreement, MareNostrum-Ona, an adiabatic quantum computer, will be hosted at the Barcelona Supercomputing Center (BSC), marking a significant milestone in the integration of quantum and supercomputing technologies across Europe.

the U.S. Department of Energy (DOE) announced $71 million in funding for 25 projects in high energy physics that will use the emerging technologies of quantum information science to answer fundamental questions about the universe.

In new work, using a superconducting qubit called fluxonium, MIT researchers in the Department of Physics, the Research Laboratory of Electronics (RLE), and the Department of Electrical Engineering and Computer Science (EECS) developed two new control techniques to achieve a world-record single-qubit fidelity of 99.998 percent. This result complements then-MIT researcher Leon Ding’s demonstration last year of a 99.92 percent two-qubit gate fidelity.

Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to temperatures close to absolute zero. Now, researchers at Chalmers University of Technology, Sweden, and the University of Maryland, USA, have engineered a new type of refrigerator that can autonomously cool superconducting qubits to record low temperatures, paving the way for more reliable quantum computation.

Oxford Instruments NanoScience has installed three ProteoxMX dilution refrigerators at the National Quantum Computing Centre (NQCC), the UK's national lab for quantum computing at their Harwell Campus. The systems will be used by the NQCC’s research team, who are developing hardware architectures based on superconducting circuits.

In an article published September 23, 2024 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. They also outlined a method to use the new qubit design in quantum simulations. While these proposed qubits might not immediately replace their more established peers, they illustrate the rich variety of quantum physics that remains to be explored and harnessed in the field.

The procurement contract of Euro-Q-Exa, the EuroHPC quantum computer to be located in Germany, has been signed by the European High Performance Computing Joint Undertaking (EuroHPC JU) and the company IQM Quantum Computers, the selected vendor.
