7. What does Quantum
means?
In Physics, a quantum (plural: quanta)
is the minimum amount of any physical
entity involved in an interaction.

8. Example:
A photon is a single quantum of
light, and is referred to as a
"light quantum". The energy of
an electron bound to an
atom (at rest) is said to be
quantized, which results in the
stability of atoms, and of matter
in general.

14. Description of each
point of
Comparison table
for all three
papers.
3/31/2013 1:11:48 AM 14

15. 1. The Problem being addressed by Paper
 Paper A: “…Among these difficulties, error correction,
decoherence and hardware architecture are probably the
most formidable.”
 Paper B: Decoherence and hardware.
 Paper C: “We are STILL striving towards developing a
large scale, quantum computer.”
3/31/2013 1:11:48 AM 15

16. 2. The Importance of the Problem
 Paper A: “A few potentially large obstacles still remain
that prevent us from building a quantum computer.”
 Paper B: “…These problems are the major obstacles in
the production of QC”.
 Paper C: N/A
3/31/2013 1:11:48 AM 16

17. 3. Prior work that has been done to solve the
problem
 Paper A: “Thanks to the theory (and now reality) of
quantum error correction, first proposed in 1995 and
continually developed since, small scale quantum
computers have been built and the prospects of large
quantum computers are looking up.”
 Paper B: N/A
 Paper C: N/A
3/31/2013 1:11:48 AM 17

18. 4. Gaps in the prior work
 Paper A: N/A
 Paper B: N/A
 Paper C: N/A
3/31/2013 1:11:48 AM 18

19. 5. Specific research questions and research
objectives
 Paper A: “…a classical computer would be able to do
anything a quantum computer can. So why bother with
quantum computers?”
 Paper B: N/A
 Paper C: To make a fully functional quantum computer.
3/31/2013 1:11:48 AM 19

20. 6. Broad outline of how the authors try to solve the
Problem Partially
 Paper A: Through the use of certain experiments.
 Paper B: “But if one makes a quantum computer, where
the number of errors is low enough, than it is possible to
use an error-correcting code for preventing data losses
even when qubits in the computer decohere.”
 Paper C: “In order to make quantum computers
powerful, many operations must be performed before
quantum coherence is lost.”
3/31/2013 1:11:48 AM 20

21. 7. Educational theories on which author’s solution is
based
 Paper A: NMR techniques.
 Paper B: “Some other designs are based on ion trap and
quantum electrodynamics (QED)...”
 Paper C: Error correcting codes.

 Paper C: N/A
3/31/2013 1:11:48 AM 23

24. 10. Connection of the results to the research
questions
 Paper A: “…quantum computers will emerge as the
superior computational devices at the very least, and
perhaps one day make today's modern computer
obsolete.”
 Paper B: N/A
 Paper C: N/A
3/31/2013 1:11:48 AM 24

25. 11. Key Contribution of the paper claimed by the
authors

 Paper B: N/A
 Paper C: “The authors dedicate this paper to Nabil Amer
and to the memory of Roger Koch.”

26. Conclusion of the above comparison
a) ‘Paper A’ does a better job of analyzing prior work to solve
the problem.
As it is able to provide the solutions for developing partially
functional quantum computers (2-3 qubit QCs).
b) ‘Paper C’ is better in terms of describing procedure.
As it describes certain algorithms.
c) ‘Paper A’ achieves its stated objective more convincingly.
As it uses experimental results rather than theoretical
aspects to resolve the problem.
