Quantum Computing and Quantum Crypto: Do we have a problem?
Quantum Computer
From : Quantum Computing: Progress & Prospects 2018. A Consensus Report. National Academy of Sciences, Engineering and Medicine (adapted from M. Mosca, 2015)
Q: Time to a quantum computer: ?
I: Time to fully change the security infrastructure: Estimate (NIST) 20yrs.
S: Shelf life: 1-50 yrs. (what is your application?)
If I+S > Q… you have problems.
Postquantum crypto: Business as usual.◦ “new” algorithms believed to be secure against Quantum
Computers.
Quantum Cryptography:◦ Physical layer security -> Networks
You need hardware
… and it is not easy
◦ Not a complete substitute!
Limited reach, point to point.
Quantum communications and networks, why is it difficult?
Δλ = 0.2~0.8 nm (DWDM)Δλ = 3~20 nm (CWDM)
Comm. laser
Single photon(not to scale)
extremely weak signals.
Noise in the fibre: Raman
Raman backscattering of a signal at 1549 nm [ DOI: 10.1063/1.1842862]
Single Photon(approx. scale)
