Quantum Physics: the study of the fundamental laws of our universe (See: Max Planck, Erwin Schrödinger, Albert Einstein)

Quantum Computing: The idea, originally proposed by Richard Feynman in the 1980s, that we can leverage quantum properties for computation – and solve problems unsolvable by classical computing

Where did this idea come from?

1982Richard Feynman envisions quantum computing

1985David Deutsch describes universal quantum computer

1994Peter Shor develops algorithm that could be used for quantum code-breaking

1999D-Wave Systems founded by Geordie Rose

2000Eddie Farhi at MIT develops idea for adiabatic quantum computing

2010D-Wave One: first commercial quantum computer, 128 qubits

A Recent History

Where did this idea come from?

• Exploits properties of quantum physics

• Built around “qubits” rather than “bits”

• Qubits are 1 or 0 and both simultaneously

• Operates in an extreme environment:

– 150x colder than interstellar space

– Shielded to 50,000× less than Earth’s magnetic field

– Very low pressure: 10B times lower than atmospheric pressure

Different Models

• Gate

• Adiabatic/annealing

• One-way

• Topological

Different Basis

• Superconducting metals

• Ion traps

• Photons

How do you build one?

• User maps a problem into search for “lowest point in a vast landscape”

• System processes an enormous search space (ex. 2 512 ) with one instruction

• Processor considers all possibilities simultaneously, finds lowest energy solutions

• Multiple solutions returned to the user, sorted by optimal probability

1. Deciding what approach will work - and scale

2. Creating the extreme operating environment

3. Manufacturing usable quantum processors

4. Proving quantum effects and understanding their impact on computation

5. Finding “the right problems” for the computer

6. Scaling processors and performance
