Computing’s Search for Quantum Questions

Recent tests show that quantum computers made by D-Wave systems should solve some problems faster than ordinary computers. Researchers have begun to map out exactly which queries might benefit from these quantum machines.


A Tricky Path to Quantum-Safe Encryption

In the drive to safeguard data from future quantum computers, cryptographers have stumbled upon a thin red line between security and efficiency.


Quantum Computing Without Qubits

A quantum computing pioneer explains why the near future of quantum computation may lie in simulators, not general-purpose quantum machines.
