Intel Touts Silicon Spin Qubits for Quantum Computing
"Intel has invented a spin qubit fabrication flow on its 300 mm process technology using isotopically pure wafers sourced specifically for the production of spin-qubit test chips. Fabricated in the same facility as Intel's advanced transistor technologies, Intel is now testing the initial wafers. Within a couple of months, Intel expects to be producing many wafers per week, each with thousands of small qubit arrays," according to the Intel news brief posted online today.
The topic isn't exactly new. Use of quantum dots for qubits has long been studied. The new Nature paper, A programmable two-qubit quantum processor in silicon, demonstrated overcoming some of the cross-talk obstacles presented when using quantum dots.
[...] Intel emphasizes silicon spin qubits can operate at higher temperatures than superconducting qubits (1 kelvin as opposed to 20 millikelvin). "This could drastically reduce the complexity of the system required to operate the chips by allowing the integration of control electronics much closer to the processor. Intel and academic research partner QuTech are exploring higher temperature operation of spin qubits with interesting results up to 1K (or 50x warmer) than superconducting qubits. The team is planning to share the results at the American Physical Society (APS) meeting in March."

Just saying, White Sharia! White guys making their biatches wear what they want them to wear, but not so hot as the other White guys, and other colored guys, and the lesbo girls, get all hot after them. . . oh, like a cover of Biker Bitches Magazine, it is to hard, almost a red pillar, if you know what I mean. Right wing men are either wooses, or gay. Long experience proves this is true. Not that there is anything wrong with that.
