What is Quantum

Quantum is “odd”

  • Superposition
  • Entanglement
  • Measurement Postulates

The quantum wave-function of a quantum object will RANDOMLY collapse to one

  • f the eigenstates of the measurement apparatuses according to the inherent

quantum statistics. The most accurate and tested theory towards the Mother Nature

  • Newton’s laws are approximation results
  • Einstein did not believe it (“God does not play dice”)
  • Experimentally verified again and again
  • Plants are exploiting quantum effects (i.e., photosynthesis)
  • We have quantum sensors (i.e., smell, vision?)

Why Quantum

To revolutionize many sectors of our society:

  • Sensing
  • Metrology
  • Imaging
  • Computing
  • Network
  • Data analytics

….

In this talk, two projects at Stevens:

Quantum random number generator

  • Trusted, randomness derived from the laws of physics
  • Programmable, tailored probability density
  • Verifiable, not relying on the statistic tests
  • Cost effective

Quantum Communication Network

  • Absolute security (eavesdropping proof)
  • Versatile
  • Compatible (existing fiber and free-space infrastructure)

Quantum Random Number Generation

Classical Approaches:

  • Measure the outcome of

“unpredictable” events

  • Flip a coin
  • Roll a die
  • Use a mathematical algorithm

Serious Problem

  • “Pseudo” random
  • seemingly random because of our

ignorance

  • random at small scale
  • Biased / repeat after some point
  • Manipulated by adversarial parties

Importance: encryption, simulation, financial analytics, optimization … Quantum Approaches:

  • Measure the outcome of stochastic

quantum processes Advantage Genuine randomness

  • Processes are inherently random.
  • Randomness guaranteed by physics,

e.g., Heisenberg uncertainty
