Microchip for room temperature quantum internet


A key requirement for a future quantum internet is that it be widely accessible and afforable. This requires the ability to  prepare mechanical systems in their lowest possible energy state  (the quantum ground state) without expensive cryogenics. Richard Norte, researcher at the Department of Precision and Microsystems Engineering, and his Delft colleagues Simon Groeblacher and Jingkun Guo have managed to design and fabricate a millimetre-long resonator on a chip, which is mechanically isolated from outside room temperature heat and noise.
