Despite the intensive worldwide race to build a useful quantum computer\, it is projected to take decades before reaching the state of useful quantum supremacy. The main challenge is that qubits operate at the atomic level\, thus are extremely fragile\, and difficult to control and read out. The current state-of-art implement s a few dozen magnetic-spin based qubits in a highly specialized technolog y and cools them down to a few tens of millikelvin. The high cost of cryog enic cooling prevents its widespread use. A companion classical electronic controller\, needed to control and read out the qubits\, is mostly realiz ed with room-temperature laboratory instrumentation. This makes it bulky a nd nearly impossible to scale up to the thousands or millions of qubits ne eded for practical quantum algorithms. We propose a new quantum computer p aradigm that exploits the wonderful scaling achievements of mainstream int egrated circuits (IC) technology which underpins personal computers and mo bile phones. Just like with a small IC chip\, where a single nanometer-siz ed CMOS transistor can be reliably replicated millions of times to build a digital processor\, we propose a new structure of a qubit realized as a C MOS-compatible charge-based quantum dot that can be reliably replicated th ousands of times to construct a quantum processor. Combined with an on-chi p CMOS controller\, it will realize a useful quantum computer which can op erate at a much higher temperature of 4 kelvin.\n\nSpeaker(s): Prof Robert Bogdan Staszewski\, \n\nAgenda: \nTime: Tuesday 20th June 14:00-15:30\n\n Format: Hybrid\n\nBldg: Roberts Building\, Lecture theatre no. 421\, \, Un iversity College London\, London \, England\, United Kingdom\, WC1E 7JE\, Virtual: https://events.vtools.ieee.org/m/420073 LOCATION:Bldg: Roberts Building\, Lecture theatre no. 421\, \, University C ollege London\, London \, England\, United Kingdom\, WC1E 7JE\, Virtual: h ttps://events.vtools.ieee.org/m/420073 ORGANIZER:a.demosthenous@ucl.ac.uk SEQUENCE:17 SUMMARY:Quantum Computing in Nanoscale CMOS URL;VALUE=URI:https://events.vtools.ieee.org/m/420073 X-ALT-DESC:Description: <br /><p class="MsoNormal" style="text-align: justi fy\;"><span lang="EN-US" style="font-size: 10.0pt\; mso-bidi-font-size: 11 .0pt\; line-height: 115%\; mso-bidi-font-weight: bold\;">Quantum computing is a new paradigm that exploits fundamental principles of quantum mechani cs\, such as superposition and entanglement\, to tackle problems in mathem atics\, chemistry and material science that are well beyond the reach of s upercomputers.
