As a highly entangled quantum network, the duster state has the potential for greater information capacity and use in measurement-based quantum computation. Here, we report generating a continuous-variable quadripartite ＂square＂ cluster state of multiplexing orthogonal spatial modes in a single optical parametric amplifier （OPA）, and further improve the quality of entanglement by optimizing the pump profile. We produce multimode en- tanglement of two first-order Hermite-Gauss modes within one beam in a single multimode OPA and transform it into a duster state by phase correction. Furthermore, the pump-profile dependence of the entanglement of this state is explored. Compared with fundamental mode pumping, an enhancement of approximately 33% is achieved using the suitable pump-profile mode. Our approach is potentially scalable to multimode entanglement in the spatial domain. Such spatial duster states may contribute to future schemes in spatial quantum information processing.

The next detectors for gravitational wave astronomy

第十八届全国量子光学学术会议

Continuous variable（CV） quantum entanglement between amplitude and phase quadratures of optical fields has been intensively investigated. Kimble’s group experimentally generated a pair of CV entangled optical beams by type-II down-conversion in a subthreshold optical parametric amplifier（OPA）. The type-II OPA compared with type-I OPA, is a vital way to generate the continuous-variable（CV） entanglement. In this context, we find that the entanglement from type II OPA is very sensitive to the phase matching condition, so that the high quality is hard to keep in long time. We propose a scheme of longterm stable entanglement generation based on phase matching temperature locking. The technology deals with the phase mismatch in the nonlinear crystal by maintaining the optimum phase matching temperature（PMT）. Based on the photothermal effect, the optimal PMT is maintained by feeding back to the crystal. Compared with the offset of 0.01 K for the commercial temperature system, this technology offers a more precise and stable temperature control. A longterm stable entanglement source lasting up to 2 hours is achieved, and experimentally obtained the entangled state of 5.4 d B. This generation of the longterm stable high quality entanglement paves the way to fully exploit the entanglement as a valuable resource in applications, such as the advanced gravitational wave detectors and fault-tolerant quantum cryptography.

This paper focuses on the next detectors for gravitational wave astronomy which will be required after the current ground based detectors have completed their initial observations, and probably achieved the first direct detection of gravitational waves. The next detectors will need to have greater sensitivity, while also enabling the world array of detectors to have improved angular resolution to allow localisation of signal sources. Sect. 1 of this paper begins by reviewing proposals for the next ground based detectors,and presents an analysis of the sensitivity of an 8 km armlength detector, which is proposed as a safe and cost-effective means to attain a 4-fold improvement in sensitivity. The scientific benefits of creating a pair of such detectors in China and Australia is emphasised. Sect. 2 of this paper discusses the high performance suspension systems for test masses that will be an essential component for future detectors, while sect. 3 discusses solutions to the problem of Newtonian noise which arise from fluctuations in gravity gradient forces acting on test masses. Such gravitational perturbations cannot be shielded, and set limits to low frequency sensitivity unless measured and suppressed. Sects. 4 and 5 address critical operational technologies that will be ongoing issues in future detectors. Sect. 4 addresses the design of thermal compensation systems needed in all high optical power interferometers operating at room temperature. Parametric instability control is addressed in sect. 5. Only recently proven to occur in Advanced LIGO, parametric instability phenomenon brings both risks and opportunities for future detectors. The path to future enhancements of detectors will come from quantum measurement technologies. Sect. 6 focuses on the use of optomechanical devices for obtaining enhanced sensitivity, while sect. 7 reviews a range of quantum measurement options.

Nonclassical optical frequency combs play essential roles in quantum computation in the continuous variable regime. In this work, we generate multimode nonclassical frequency comb states using a degenerate type-I synchronously pumped optical parametric oscillator and directly observe the squeezing of the leading five temporal modes of femtosecond pulsed light. The overlapping spectra of these modes mean that the temporal modes are suitable for use in real-world quantum information applications.
