PowerBank Powers Room-Temperature Electronics for Quantum Computer Chip Fab
Quantum computing, a new kind of computing, is not likely to replace digital computers in the foreseeable future. Instead of using two states, 0 and 1, on or off, the quantum computer can use both 0 and 1 at the same time, and all points in between, whatever that means. And instead of performing one calculation at a time, the quantum computer can perform many calculations at once. Calculations using quantum bits (qubits) have been accomplished, although the number of qubits involved to date have been quite small. The achievable performance of quantum computers is predicted to be astronomical, far in excess of today’s supercomputers, that is, in the millions of times more powerful. An obvious application for such a computer would be cryptography, enciphering and deciphering of messages. The point has been made that if one of these computers existed today, everything on the Internet would be open to attack or access.
The Vicor customer is working to develop such a machine, and has achieved some success, in three-digit qubits. Their approach uses superconducting electronics for their chip, which operates at ultra-low temperatures in a magnetic vacuum. Room-temperature electronics drive the analog, digital, and power lines for the chip. The electronics must be very low noise in order for it to not disturb the quantum calculation. A Vicor PowerBank AC-DC power supply is used to power the room-temperature electronics.
The PowerBank supply meets the conducted noise requirements of EN55022, Class A from 150 kHz to 30 MHz. It has an input voltage range of 90 – 264 Vac and has six outputs of 4.5, 4,5, 6, 6, 6, 6; total power is 1,500 W.
