This document discusses the history and future of quantum computing. It begins with a brief history of quantum computing from the early 1900s work of Planck, Heisenberg, Schrodinger and Einstein establishing quantum theory. It then discusses key developments like Feynman's proposal of a quantum computer in 1981 and Shor's algorithm in 1994. The document notes the first simple quantum computations in the late 1990s and D-Wave's first commercial 28-bit quantum computer in 2007. It explains how quantum computers use superposition and parallelism differently than classical computers. While quantum computers may be useful for some problems like optimization, dynamic portfolio management and trading strategy research, their advantages are still being explored. The document concludes that while quantum

history

4. Early 1900’s: Planck, Heisenberg, Schrödinger, Einstein -
in the small universe energy exists in little discrete
amounts – ‘quanta'

5. 1981 Richard Feynman:
some problems cannot be
solved by a regular
computer, proposed the
idea of a quantum
computer.

6. 1994 Peter Shor: a
computer which uses
zeros and ones at the
same time could speed
up certain calculations.

7. Grover and others follow building algorithms for yet non
existing hardware.

8. Late 90’s: the first
simple calculations are
carried out on bulky
hardware.

9. 2007: D-Wave
comes up with
the first
commercial 28-
bit quantum
computer.

10. Since then technology has improved
steadily and basic QC resources and
programming tools are now available
to the public.

12. How does a Quantum computer work?

13. In a normal computer we have zeros and ones processed
sequentially.

14. In a QC they exist at the same time and ask combinations
can be calculated simultaneously.

15. It's not faster than a normal computer.

16. Rather it's like lots of computers in parallel.

17. So QCs are ideal for specific types of problems where
parallel calculations are carried out.

18. For a lot of problems QCs don't have an advantage.

19. QC won't lead
to faster HFT.

20. The quantum future of finance

21. We don't really know yet what
quantum computing can
actually accomplish. Like in
the sixties nobody could
conceive the cloud or social
media.

22. Whilst machine learning and AI is
still new to finance, it is already
beginning to be implemented on
QCs.

23. Right now, very few people
understand how to program a
quantum algorithm as it needs a
new way of thinking.

24. We will see more people adopting it.

25. Quantum finance for example looks
at the Black Scholes equation for
option pricing as a special case of
the Schroedinger equation.

26. Some problems are hard to solve
and finance has a lot of them.

27. Dynamic portfolio
optimization.

research. But we are still a few
years away from
sizable hardware.
Large boost in
innovation.
Currently only
interesting to
experts.
The demand for
quantum
programmers in
finance will grow.
Quantum computers
are here and getting
better.
Desktop quantum
computers are still
a very long way
away.

28. What might this mean for
tomorrow?

29. QC will mostly be in
the cloud.

30. More sophisticated firms will
adopt the technology early.

31. The demand for quantum
programmers in finance will grow.

32. Steady decline
of manual
trading
continues.
