Patent for Faster than Light Communication Device

[wa1ex]

A method and apparatus for transmitting information using the

 

phenomenon of quantum entanglement. Two streams of quantum-entangled particles

 

are emitted from a source.

 

Performing a measurement on one of the streams results in the observable

 

destruction of interference on the other stream.

 

Information is transmitted by modulating the performance of the measurement

 

on the first stream, and received by observing the presence or absence of

 

interference in the second stream.

Re: Patent for Faster than Light Communication Dev

 

Claims:

 

1. Communications apparatus comprising: A) means for generating pairs of particles that are quantum mechanically entangled with respect to a quantum state variable, said particle pairs being arranged as a first beam of particles and a second beam of particles, where every particle in said first beam of particles has its quantum entangled counterpart in said second beam of particles (and vice versa), B) a receiver comprising 1) means for separating the particles in said first beam of particles into a third beam of particles and a fourth beam of particles according to the value of said quantum mechanical state variable, 2) means for recombining said third and fourth beam of particles in such a manner as to generate quantum interference, and 3) means for detecting the presence or absence of quantum interference in said recombining means, and C) a transmitter comprising 1) means for separating the particles in said second beam of particles that is capable of separating the particles either according to the value of said quantum state variable or according to the value of the quantum state variable that is orthogonal to said quantum state variable, the mode of separation being selectable at the time when the invention is in operation, 2) means for selecting said mode of separation of said separating means, and 3) means for absorbing the particles emitted by said separating means.

 

2. The communications apparatus of claim 1 where said means for generating particle pairs comprise a laser and a down-converter.

 

3. The communications apparatus of claim 1 where any of said separating means comprise a polarizing beam splitter.

 

4. The communications apparatus of claim 1 where the receiver comprises a Mach-Zender interferometer.

 

5. The communications apparatus of claim 1 where all the particle beams are beams of electrons and said separating means comprise a Stem-Gerlach apparatus.

 

6. A method of communication using the apparatus of claim 1 where information is transmitted by selecting the mode of operation of said separating means in the transmitter.

 

7. The communications apparatus of claim 1 where all the particle beams are beams of photons.
