The Five 'Must Haves' To Make Your Own Quantum Computer

Listen

Description

What if someone handed you the recipe for a quantum computer? In this episode, that’s exactly what happens.

Coleman Collins of IonQ breaks down DiVincenzo’s criteria, (a checklist proposed by physicist David DiVincenzo) the five capabilities any physical system needs before it can call itself a quantum computer. 

There are five criteria.

  1. A well-defined qubit
  2. Ability to initialize qubits. You must be able to reliably set every qubit to a known starting state.
  3. Long coherence times. The qubits must remain stable long enough to run operations without losing their quantum state.
  4. Ability to measure qubits. You need to read the state of each qubit at the end of the computation (ideally individually).
  5. A universal gate set built from entanglement and single-qubit control.

Mix them all together in a serving bowl and these let you perform any quantum computation you wish.

You now know the foundation behind every major quantum architecture, from superconducting circuits to trapped ions.

Cheers, 

Mark and Jeremy.
