Quantum physics and time

From Wikipedia: Vlatko Vedral is a Serbian-born (and naturalised British citizen) physicist and Professor of Physics at the University of Oxford and CQT (Centre for Quantum Technologies) at the National University of Singapore and a Fellow of Wolfson College. He is known for his research on the theory of Entanglement and Quantum Information Theory. As of 2017 he has published over 280 research papers in quantum mechanics and quantum information and was awarded the Royal Society Wolfson Research Merit Award in 2007. He has held a Lectureship and Readership at Imperial College, a Professorship at Leeds and visiting professorships in Vienna, Singapore (NUS) and at Perimeter Institute in Canada. As of 2017, there were over 18,000 citations to Vlatko Vedral’s research papers. He is the author of several books, including Decoding Reality.

Watch this movie “Living in a quantum world” from Vlatko Vedral on YouTube: https://youtu.be/vaUfZak8Ug4. At the end of his presentation a question from the audience about time and quantum physics is asked (at about 1: 10) and in his answer he describes the behavior of a super-accurate clock and what happens to the last digits when you lift that clock half a meter in the gravitational field. And then he wonders what it means when you imagine that clock to be in a quantum superposition at the two different heights in the gravitational field. A superposition of two different timelines. Fascinating.

By the way, the first part of his presentation – about 45 minutes – is actually a very compact version of my quantum physics book. Everything is presented in an almost blazing speed: interference, the Mach-Zehnder interferometer, Schrödinger’s cat, the Copenhagen interpretation against the multiverse interpretation, delayed choice experiments, interference with very large molecules shot through double slits, the orientation of our robin on the earth’s magnetic field in its annual migration, the 100% efficiency of chlorophyll. Highly recommended.


The 2019 SSE Conference will be held June 5-8 at the beautiful Omni Interlocken Hotel in Broomfield, Colorado.

I’m invited to do a poster presentation on June 7 2019 at the SSE conference on consilience. Here is the text of my submission paper:

Submission presentation SSE – english

Interpretations of quantum physics trying to save the idea of an objective reality existing outside us will not survive critical examination of their explanation of the so-called quantum collapse. The following interpretations will be tackled:

  • Kopenhagen macro apparatus interpretation,
  • Decoherence,
  • Super selection,
  • Hidden variables,
  • Multiversa,
  • Spontaneous quantum collapse.

However other interpretations that do accept the connection between the conscious observer and quantum reality confer the problem of the nature of this connection to a more or less magical action on physical reality by a non-physical consciousness. Something I often refer to as ‘Harry Potter’ magic. These interpretations are:

  • The Matrix,
  • No quantum collapse whatever,
  • Von Neumann Projection Postulate.

Those three interpretations and the Kopenhagen interpretation do recognize the quantum wave being a non-physical possibility wave. The quantum wave function gives the time and location dependent possibility to find the quantum particle in a measurement. Because the mathematic expression for the quantum wave describes a probability, which is also nowhere exact null, the wave should be regarded as just as non-local as a thought. These interpretations acknowledging the role of consciousness do not however solve these problems:

  1. how works consciousness its effect on the non-physical quantum possibility wave,
  2. how it is possible that multiple observer minds manifest the same outcome? When I observe the moon, I’m surely not the only one so how can I possibly manifest the moon?
It’s really all in our mind
