Fractally-Structured CMOS Processor for Quantum-Circuit Emulation
S. O’uchi, Minoru Fujishima, Koichiro Hoh · Japanese Journal of Applied Physics · 2002
A novel complementary-metal-oxide-semiconductor (CMOS) processor labelled quantum-circuit processor (QCP) for the high-performance emulation of quantum computing is presented. The QCP performs the emulation of the calculation performed in the quantum circuit by simple matrix calculations based on single-instruction-stream-multiple-data-stream (SIMD) parallel processing. Using the parallel operation of an enormous number of devices in LSI, it executes quantum algorithms at a speed comparable to that of the quantum computer. A 5-qubit processor was implemented using a programmable logic device (PLD), and the quantum Fourier transformation was demonstrated by this processor.
