If the goal is to make quantum systems act like powerful classical machines, then today’s quantum computers may be too ...

Bitcoin's mining and ledger are built on SHA-256, a hash function that quantum computers cannot efficiently break. That means ...

“We demonstrated a so-called universal gate set—meaning that if you store information in these emergent versions of quarks, and you move them around, you can do any quantum computation you might want ...

IBM and researchers from the University of Chicago announced a demonstration in quantum computing that meets the fundamental ...

Semiconductor spin qubits are one of the most promising building blocks for future quantum computers, but turning them into a working, large-scale quantum computer has so far proven difficult. For now ...

“However, a quantum computer can only function properly if its qubits are not disturbed too much,” Schützhold emphasizes. Engineers protect qubits by shielding them from electromagnetic radiation and ...

IBM CEO Arvind Krishna said the company's investments in quantum computing should begin to have "a measurable impact" on revenue and earnings by 2028 or 2029.

IBM and research partners show how quantum calculations can be checked for accuracy in real time in three new papers.
