- Abstract: A novel method of macroscopically entangled light-pair generation is
presented for a quantum laser using randomness-based deterministic phase
control of coherent light in a Mach-Zehnder interferometer (MZI). Unlike the
particle nature-based quantum correlation in conventional quantum mechanics,
the wave nature of photons is applied for collective phase control of coherent
fields, resulting in a deterministically controllable nonclassical phenomenon.
For the proof of principle, the entanglement between output light fields from
an MZI is examined using the Hong-Ou-Mandel-type anticorrelation technique,
where the anticorrelation is a direct evidence of the nonclassical features in
an interferometric scheme. For the generation of random phase bases between two
bipartite input coherent fields, a deterministic control of opposite frequency
shifts results in phase sensitive anticorrelation, which is a macroscopic
quantum feature.

Quantum entanglement between paired photons is the foundation of optical quantum computing, quantum sensing, and quantum networks.
Recently, a coherence-based approach has been explored to understand the so-called quantum mystery of nonlocal intensity fringes emerging from local randomness.
Here, a pure coherence method is presented to create macroscopic quantum features using conventional laser light via linear optics-based measurement modifications.

We study a model of amplification of quantum transfer and making it directed which we call the quantum ratchet model.
The ratchet effect is achieved in the quantum control model with dissipation and sink, where the Hamiltonian depends on vibrations in the energy difference synchronized with transitions between energy levels.
Amplitude and frequency of the oscillating vibron together with the dephasing rate are the parameters of the quantum ratchet which determine its efficiency.
