Are we living in The Matrix

[2017-01-11 Wed 19:16:29] speaker: Howard Wiseman event: Science in the Cafe

A hidden level of information processing behind the observed reality.

Heisenberg: represent a physical quantity with an infinitly large matrix, it is possible to derive properties of atoms like their quantized energy levels.

The Copenhagen Interpretation (1927)

• it is the act of measurement itself which creates the measured value

Bell’s Theorem (1964)

• Einstein was wrong, hidden variables cannot remove action at a distance

Experimental verification of Bell’s non locality in 2015

Explaining Bell-type quantum correlations with a game by P. K. Arvind

• team of 2 vs the referee
• 3x3 matrix of zeros and ones
• a magic matrix
  • each column has an even number of ones
  • each row has an odd number of ones
• not possible to construct such a matrix as the number of ones is either odd or even
• in a trial, ask for one row and one column
  • will get at least 1/9 of the trials wrong
• with entangled particles, it is possible to be right all the time

Applications of entanglement

• Bell-type correlation to enable absolutely secure communication
• quantum teleportation
• quantum computing

Difference interpretations

• Bohr
• Everett
• Bohm
