Quantum Computing

---

There are many questions to be answered and many problems to be overcome for quantum computing to be feasible for problem solving.

• How are quantum bits entangled?
  (How do you apply a 'gate' to two (or more) quantum bits?)

• How do you know if two quantum bits are really entangled?

• How do you know if a 'computation' is ready?
  (How do you know if the system is stabilized so that it contains the solution(s)?)

• How do you know if the solution is right?

• How do you get all the solutions or another solution?
