• Abstract: The quantum illumination is examined by making use of the three-mode maximally entangled Gaussian state, which involves one signal and two idler beams. It is shown that the quantum Bhattacharyya bound between $\rho$ (state for target absence) and $\sigma$ (state for target presence) is less than the previous result derived by two-mode Gaussian state when $N_S$, average photon number per signal, is less than $0.295$. This indicates that the quantum illumination with three-mode Gaussian state gives less error probability compared to that with two-mode Gaussian state when $N_S < 0.295$.

• Multi-mode Gaussian State Analysis with one Bounded Photon Counter [0.0]
  What properties of a multi-mode Gaussian state are determined by the signal from one detector that measures total number photons up to some bound? We find that if the Gaussian state occupies $S$ modes and the probabilities of $n$ photons for all $nleq 8S$ are known, then we can determine the spectrum of the Gaussian covariance matrix. Nothing more can be learned, even if all photon-number probabilities are known.

Third, we show that it is of utmost importance to prepare an efficient idler memory to beat coherent states and provide analytic bounds on the idler memory transmittivity in terms of signal power, background noise, and idler memory noise.

  We study the distribution over measurement outcomes of noisy random quantum circuits in the low-fidelity regime. For local noise that is sufficiently weak and unital, correlations (measured by the linear cross-entropy benchmark) between the output distribution $p_textnoisy$ of a generic noisy circuit instance shrink exponentially. If the noise is incoherent, the output distribution approaches the uniform distribution $p_textunif$ at precisely the same rate.

  Universal quantum computing with continuous variables requires non-Gaussian resources. The cubic phase state is a non-Gaussian state whose experimental implementation has so far remained elusive. We introduce two protocols that allow for the conversion of a non-Gaussian state to a cubic phase state.

  We present optimal schemes, based on photon number measurements, for Gaussian state tomography and for Gaussian process tomography. Our scheme requires exactly $2 n2+3n$ distinct photon number measurements to tomograph the state and is therefore optimal. With much recent progress in photon number measurement experimental techniques, we hope that our scheme will be useful in various quantum information processing protocols.

• Bosonic quantum communication across arbitrarily high loss channels [68.58838842613457]
  A general attenuator $Phi_lambda, sigma$ is a bosonic quantum channel that acts by combining the input with a fixed environment state. We show that for any arbitrary value of $lambda>0$ there exists a suitable single-mode state $sigma(lambda)$. Our result holds even when we fix an energy constraint at the input of the channel, and implies that quantum communication at a constant rate is possible even in the limit of arbitrarily low transmissivity.

  We give scalable, explicit digital quantum algorithms to simulate the lattice Schwinger model in both NISQ and fault-tolerant settings. In lattice units, we find a Schwinger model on $N/2$ physical sites with coupling constant $x-1/2$ and electric field cutoff $x-1/2Lambda$. We estimate observables which we cost in both the NISQ and fault-tolerant settings by assuming a simple target observable---the mean pair density.
