PHYSICISTS PROPOSE A MODULAR QUANTUM COMPUTER ARCHITECTURE
THAT OFFERS SCALABILITY TO LARGE NUMBERS OF QUBITS
How do you build a universal quantum computer? Turns out,
this question was addressed by theoretical physicists about 15 years ago. The
answer was laid out in a research paper and has become known as the DiVincenzo
criteria [See Gallery Sidebar for information on this criteria]. The
prescription is pretty clear at a glance; yet in practice the physical implementation
of a full-scale universal quantum computer remains an extraordinary challenge.
