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

• 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

• 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
