We study a generic model of quantum computer, composed of many qubits coupled by short-range interaction. Above a critical interqubit coupling strength, quantum chaos sets in, leading to quantum ergodicity of the computer eigenstates. In th...

Quantum computing has been heralded by some as the death of cryptography as we know it. Yet the quantum computers that exist today can't perform more complex operations than tasks such as factoring 15 into 3×5, so they're pretty useless. A ...
