A quantum computer also needs memory: seven selectively accessible storage cells

Researchers have demonstrated a quantum random-access memory in a superconducting circuit. One of seven storage modes can be selected via a shared switching station, but the road to a large computer is still a long way off.
Two cryogenic cooling modules connected to IBM quantum computers

IBM has connected two modular quantum supercoolers on the way to systems of thousands of qubits

Both cooling modules have reached temperatures below 15 millikelvins and offer up to 12 times more wiring space than existing IBM systems. This is a demonstration of an infrastructure designed to enable the connection of many processors — not yet

Australian research team discovers why quantum computers have “memory problems” over time

Researchers have found that the tiny errors that plague quantum computers don't appear randomly. Instead, they can remain in the computer, evolve over time, and even connect with each other across time.
