Characterizing Large-Scale Quantum Computers via Cycle Benchmarking

Characterizing large-scale quantum computers via cycle benchmarking

Quantum computers promise to solve certain problems more efficiently than their digital counterparts. A major challenge towards practically useful quantum computing is characterizing and reducing the various errors that accumulate during an algorithm running on large-scale processors. Current characterization techniques are unable to adequately account for the exponentially large set of potential errors, including cross-talk and other correlated…

Quantum computers could render even our most secure systems obsolete

Quantum computers could revolutionize the solving of complex math problems... and break into just about anything. Panagiotis (Panos) Vlachos: Satellit...

With quantum cryptography and key exchange: 16 connected stations are to form the largest network for quantum communication. (Telecommunication, encryption)

Everywhere you hear and read about the threat from quantum computers. But how close is the cryptocalypse really? The current episode gets to the bottom of this.
