Typical superconducting quantum circuits, such as qubits—basic processing units of a quantum computer, must be operated at very low temperatures, of a few 10s of millikelvin, or hundredths of a degree from absolute zero temperature. […]
The day Russian tanks rolled into Ukraine the infamous 2019 words of President Macron – NATO is ‘brain dead’ – were crushed under its tracks. President Putin failed to conquer Ukraine. He succeeded in reinvigorating […]
As Europe looks to strengthen its case as a global leader in critical quantum technologies, the Polytechnic University of Madrid (UPM) took part in a demonstration that shows the university is at the forefront of […]
Insider Brief Terra Quantum researchers report they set a world record for securing long-distance communications with quantum encryption. The company said it successfully sent quantum-secure communication on optical-fiber cables over 1,032 kilometers at significantly higher […]
HRL Laboratories in Malibu, California is another group working on creating qubits using quantum dot (also known as spin qubit) technology. The have developed a 6 quantum dot, 2 qubit prototype device they call SLEDGE. […]
Although today’s best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from the spin statistics of the many atoms they interrogate, known as quantum projection […]
A photo shows one of Intel’s Tunnel Falls chips on a human finger to display its scale. Silicon spin qubits are up to 1 million times smaller than other qubit types. The Tunnel Falls chip […]
A counterintuitive facet of the physics of photon interference has been uncovered by three researchers of Université libre de Bruxelles, Belgium. In an article published this month in Nature Photonics, they have proposed a thought […]
As with so much in mathematics, the proof started with coffee. In September 2019, Kathryn Mann of Cornell University visited Kingston, Ontario, to give a guest lecture at Queen’s University. Afterward, she sat down with […]
Insider Brief Intel announced the release of its newest quantum research chip, Tunnel Falls, a 12-qubit silicon chip. Tunnel Falls is fabricated on 300-millimeter wafers in the D1 fabrication facility. The company will also make […]
