The elevator pitch on quantum computers

So, what’s a quantum computer?

Single sentence definition for quantum computer

A quantum computer is a specialized electronic device which is able to perform a fairly small calculation on a very large number of possible solution values all at once using a process known as quantum parallelism, producing a solution value in a very short amount of time.

The elevator pitch on quantum computing

What is quantum computing?

The essence of quantum computing: exploiting the inherent parallelism of a quantum computer

At its essence, quantum computing enables a quantum application to exploit the inherent parallelism of a quantum computer to evaluate a very large number of potential solutions to a relatively small computation all at once, delivering a result in a very short amount of time.

What is a practical quantum computer?

As already mentioned, quantum computers are still in their infancy and not ready for practical use. So, what is a practical quantum computer? By definition:

  • A practical quantum computer supports production-scale practical real-world quantum applications and achieves dramatic quantum advantage over classical computing and delivers extraordinary business value which is well beyond the reach of classical computing.

What is practical quantum computing?

Practical quantum computing is the fruition of quantum computing, when practical quantum computers themselves come to fruition, coupled with all of the software, algorithms, applications, and other components of quantum computing.

The quantum computing sector

Some may consider quantum computing to be an industry or field, but for the purposes of this informal paper I consider quantum computing to be a sector of the overall computing industry — the quantum computing sector.

For more detail

To go beyond the elevator pitches, I have two long but informal papers:

And for a lot more detail

And for the bigger — and deeper — picture on quantum computing, here’s my suggested reading list for those attempting to get started in quantum computing:

  1. What Is Quantum Computing?
  2. What Is a Quantum Computer?
  3. What Is Quantum Information?
  4. What Is Quantum Information Science?
  5. What Are Quantum Effects and How Do They Enable Quantum Information Science?

Postscript — recent debate over hype and potential for quantum computing

These are some comments I made on a LinkedIn post concerning recent debate over hype and potential for quantum computing…

My original proposal for this topic

For reference, here is the original proposal I had for this topic. It may have some value for some people wanting a more concise summary of this paper.

  • Quantum computing elevator pitch. What is quantum computing, and why should you care? What is it — in theory, ideally? What is it actually today? What is it expected to be by the end of the year? What is it expected to be in two years? What is it expected to be in five years? What is it expected to be in ten years? One or two short paragraphs, or maybe three or four very short paragraphs at most. May need multiple pitches for different audiences. See also: Single paragraph introduction to quantum computing.
