The high-order sideband generation in a gently modulating optomechanical system, which consists of a standard optomechanical system driven by a mildly amplitude modulated field (MAMF) is investigated. It is found that the sideband generation can be effectively optimized by choosing an appropriate component number N of the MAMF, and this scheme can generate more and flatter high-order sidebands with the same input power compared with the conventional model. The efficiency of the sideband generation is much superior to the traditional scheme. The challenge for high-efficiently realizing a flat optical frequency comb based on optomechanical systems may be aided by this work.

“…Optomechanical systems (OMSs) have been exploited in different areas of quantum technologies, such as quantum information processing and communication [1][2][3][4], quantum memories [5,6], reversible microwave-to-optics converters [7][8][9][10][11], microwave circulators [12,13], quantum correlations [14][15][16][17][18], quantum squeezing [19,20], as well as in fundamental physics [21][22][23][24][25][26][27][28][29][30].

In this paper, we propose an experimentally viable scheme to enhance the sensitivity of force detection in a hybrid optomechanical setup assisted with squeezed vacuum injection, beyond the standard quantum limit (SQL). The scheme is based on a combination of the coherent quantum noise cancellation (CQNC) strategy with a variational homodyne detection of the cavity output spectrum in which the phase of the local oscillator is optimized. In CQNC, realizing a negative-mass oscillator in the system leads to exact cancellation of the backaction noise from the mechanics due to destructive quantum interference. Squeezed vacuum injection enhances this cancellation and allows sub-SQL sensitivity to be reached in a wide frequency band and at much lower input laser powers. We show here that the adoption of variational homodyne readout enables us to enhance this noise cancellation up to 40 dB compared to the standard case of detection of the optical output phase quadrature, leading to a remarkable force sensitivity of the order of 10 −19 N/ √Hz, 2-order enhancement compared to the standard case. Moreover, we show that at nonzero cavity detuning, the signal response can be amplified at a level 3-to 5-times larger than that in the standard case without variational homodyne readout, improving the signal-to-noise-ratio (SNR).

Quantum teleportation, the faithful transfer of an unknown input state onto a remote quantum system [1], is a key component in long distance quantum communication protocols [2] and distributed quantum computing [3,4]. At the same time, high frequency nano-optomechanical systems [5] hold great promise as nodes in a future quantum network [6], operating on-chip at low-loss optical telecom wavelengths with long mechanical lifetimes. Recent demonstrations include entanglement between two resonators [7], a quantum memory [8] and microwave to optics transduction [9][10][11]. Despite these successes, quantum teleportation of an optical input state onto a long-lived optomechanical memory is an outstanding challenge. Here we demonstrate quantum teleportation of a polarizationencoded optical input state onto the joint state of a pair of nanomechanical resonators. Our protocol also allows for the first time to store and retrieve an arbitrary qubit state onto a dual-rail encoded optomechanical quantum memory. This work demonstrates the full functionality of a single quantum repeater node, and presents a key milestone towards applications of optomechanical systems as quantum network nodes.
