Future of massively parallel computing

For real?

A future of massively parallel computing

Definitions by Michele Mosca

1. Since the world is quantum, any computer is a quantum computer. Conventional

computers are just weak quantum computers, since they don’t exploit intrinsically quantum effects,

such as superposition and entanglement.

2. A quantum computer is a computer that uses intrinsically quantum effects that cannot naturally be

modeled by classical physics. Classical computers may be able to mathematically simulate instances

of such computers, but they are not implementing the same kinds of quantum operations.

3. A quantum computer is a computer that uses intrinsically quantum effects to gain some advantage

over the best known classical algorithms for some problem.

4. A quantum computer is a computer that uses intrinsically quantum effects to gain an asymptotic

speed-up over the best known classical algorithms for some problem.

5. A quantum computer is a computer that is able to capture the full

computational power of quantum mechanics, just as conventional computers are

believed to capture the full computational power of classical physics.

Data

● Entangled states● Superpositions

Operations

● Unitary time evolution● Measurement

Scam or not

Environment requirements

A Unique Processor Environment● Shielded to 50,000× less than Earth’s magnetic field

● In a high vacuum: pressure is 10 billion times lower than atmospheric pressure

● 192 i/o and control lines from room temperature to the chip

● "The Fridge" and servers consume just 15.5kW of power

● Power demand won’t increase as it scales to thousands of qubits

If you take just one piece of info from this talk:

Quantum computers would not solve hard search problems by using superpositions to try all the candidate solutions at once.
