Common knowledge suggests that trajectories of particles in quantum mechanics always have quantum uncertainties. These quantum uncertainties set by the Heisenberg uncertainty principle limit precision of measurements of fields and forces, and ultimately give rise to the standard quantum limit in metrology. With the rapid developments of sensitivity of measurements these limits have been approached in various types of measurements including measurements of fields and acceleration. Here it is… 
Monitoring of dynamical phase-space trajectories with sub-Heisenberg indeterminacy
The Heisenberg uncertainty relation describes the fact that the phase-space trajectory of a single quantum system cannot be precisely determined with respect to semi-classical reference values to
Quantum back-action-evading measurement of motion in a negative mass reference frame
It is shown that QBA on a macroscopic mechanical oscillator can be evaded if the measurement of motion is conducted in the reference frame of an atomic spin oscillator, and this hybrid quantum system paves the way to entanglement generation and distant quantum communication between mechanical and spin systems and to sensing of force, motion and gravity beyond the standard quantum limit.

Entanglement between distant macroscopic mechanical and spin systems
Entanglement is an essential property of multipartite quantum systems, characterized by the inseparability of quantum states of objects regardless of their spatial separation. Generation of
Quantum limits for stationary force sensing
Interferometric force and position sensors have reached the sensitivity where the quantum noise of the meter, e.g., light, is significant or even dominant. In particular, this sensitivity is close to
Quantum-mechanics-free subspaces in composite systems with incompatible energy spectra
It is well established that quantum back action (QBA) can be reduced (or even completely canceled) in composite systems by engineering so-called quantum-mechanics-free subspaces (QMFSs) of commuting
Gravitational wave detection beyond the standard quantum limit using a negative-mass spin system and virtual rigidity
Gravitational wave detectors (GWDs), which have brought about a new era in astronomy, have reached such a level of maturity that further improvement necessitates quantum-noise-evading techniques.
Quantum non-demolition measurements of moving target states
We present a protocol for probing the state of a quantum system by its resonant coupling and entanglement with a meter system. By continuous measurement of a time evolving meter observable, we infer
Subsystems for all-optical coherent quantum-noise cancellation
Quantum mechanics dictates that a measurement always disturb the measured system. In weak continuous measurements, the trade-off between measurement precision and back-action onto the system yields
Optical backaction-evading measurement of a mechanical oscillator
This work demonstrates a backaction-evading measurement of the motion of a nanomechanical beam using laser light, and observes up to 0.67 dB (14%) reduction of total measurement noise, thereby demonstrating the viability of backaction -evading measurements in nanomechical resonators for optical ultrasensitive measurements of motion and force.


Evading quantum mechanics
Quantum mechanics is potentially advantageous for certain information-processing tasks, but its probabilistic nature and requirement of measurement back action often limit the precision of

Perfection of the technique of macroscopic physical experiments has recently been proceeding so intensively that we can now inquire naturally under what conditions in macroscopic experiments will an
Mechanically detecting and avoiding the quantum fluctuations of a microwave field
Continuous two-tone back-action evading measurements with a superconducting electromechanical device is presented, realizing three long-standing goals: detection of back- Action forces due to the quantum noise of a microwave field, reduction of this quantum back- action noise by 8.5 decibels, and measurement imprecision of a single quadrature of motion 2.4 ± 0.7 dB below the mechanical zero-point fluctuations.

Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete.
