A quantum computer (QC) is a new paradigm that exploits basic principles of quantum mechanics, such as entanglement and superposition. It potentially enables unprecedented speedups in solving intractable problems in, for example, prime factorization for encryption, quantum simulations for synthesis of drugs and materials, and complex optimizations. The potential of QC is so enormous that it can irreversibly change the future of computing as well as information storage and communications. In its fundamental embodiment, a QC comprises a quantum processor and a classical electronic controller. The quantum processor consists of a set of quantum bits (qubits) operating at extremely low temperatures, typically a few tens of mK, while the classical electronic controller is used to read out and control the quantum processor, and is typically implemented today with room-temperature laboratory instruments. A recent work in which this applicant was involved at TU Delft has proposed a monolithic integration of the read-out and control circuitry in a standard CMOS technology operating at cryogenic temperatures (cryo-CMOS). Although other specialized electronic technologies can handle cryogenic temperatures, only CMOS can work down to at least 30mK while providing complex system-on-chip (SoC) integration capable of handling thousands or millions of qubits necessary for realistic QC algorithms. A drastic reduction of the complex interconnections between the cryogenic chamber and room-temperature electronics will result in enhanced compactness and reliability, thus paving the way to the creation of practical quantum computers. This talk addresses such issues of building a practical QC.c
