Abstract
We propose a method for quantum enhanced phase estimation based on continuous variable (CV) quantum teleportation. The phase shift probed by a coherent state can be enhanced by repeatedly teleporting the state back to interact with the phase shift again using a supply of two-mode squeezed vacuum states. In this way a sequential protocol exhibiting both super-resolution and super-sensitivity can be obtained due to the coherent addition of the phase shift. The protocol enables Heisenberg-limited sensitivity and super-resolution given sufficiently strong squeezing. The proposed method could be implemented with current or near-term technology of CV teleportation.
Quantum metrology: Enhancing measurements with quantum teleportation
A strategy for enhancing optical phase measurements is proposed that exploits quantum teleportation. The ability to make highly sensitive measurements underpins modern science. Quantum effects can be used in a number of ways to enhance the sensitivity of certain measurements, but most approaches in quantum metrology exploit quantum entanglement, which can be challenging to implement in some systems. A team of researchers in Denmark, led by Johannes Borregaard from the University of Copenhagen, now propose an alternative strategy for quantum-enhancing phase measurements, which is based on quantum teleportation. Their idea is to enhance optical phase measurements by repeatedly teleporting back the probe to interact with a phase shift multiple times. This sequential protocol should enable both super-resolution and super-sensitivity, and could be implemented using current or near-term technology.
