Understanding a molecule that plays a key role in nitrogen fixing – a chemical process that enables life on Earth – has long been thought of as problem for quantum computers, but now a classical computer may have solved it

Quantum computing, what can it do?

[–] ProbablyBaysean@lemmy.ca 2 points 3 months ago (3 children)

So classical computers have bits where if electricity is on then it is a 1 and if it is off, then jt js a 0. This scales up with base 2 numbers and we have a lot of optimization here. 5 bits allow 5 digits with each 1 value.

Quantum computers use qbits which are superimposed on each other so a quantum computer with 5 qbits has 5! Or 120 values. They should be really efficient on certain tasks, but not generally efficient.
