Purdue University Researchers Develop Wavelength-Selective Switch for Quantum Networking
A quantum internet is closer to reality, thanks to this switch When quantum computers become more powerful and widespread, they will need a robust quantum internet to communicate. Purdue University engineers have addressed an issue barring the development of quantum networks that are big enough to reliably support more than a handful of users. The […]
Rice University: Spintronic Device Research to Improve Next-Generation Quantum Computers
Theory accelerates push for spintronic devices Rice models help ID materials for advanced electronics, computer memories A new theory by Rice University scientists could boost the growing field of spintronics, devices that depend on the state of an electron as much as the brute electrical force required to push it. Materials theorist Boris Yakobson and graduate student Sunny […]

Abstract: Microsoft and University of Sydney Study Signals for Controlling Scaled Qubits – Lots of Them
A cryogenic CMOS chip for generating control signals for multiple qubits Abstract + Scaled-up quantum computers will require control interfaces capable of the manipulation and readout of large numbers of qubits, which usually operate at millikelvin temperatures. Advanced complementary metal–oxide–semiconductor (CMOS) technology is an attractive platform for delivering such interfaces. We estimate that a scaled-up system […]
Fighting Back: 10 miliKelvins Will Destroy Your Qubits
Cooling quantum computers Read More… + To keep systems in a quantum state, designers have to minimize the risk of anything disrupting the fragile position. The slightest temperature increase can mean that atoms and molecules move around too much, potentially causing a quantum bit (qubit)’s voltage to spike, and flip from one quantum state to […]
