Learning quantum states - aka #quantum state tomography - is actually strangely difficult and sample inefficient for #continuousvariable states. For #Gaussian states, it should be efficient and relatively easy. In this work, we find an energy independent way of performing tomography of Gaussian states, equipped with rigorous performance guarantess, and one that requires offline squeezing and feasible passive optics only.

The infinitude of the #continuousvariable (CV) phase space is a serious obstacle in designing randomized tomography schemes with provable performance guarantees. A typical strategy to circumvent this issue is to impose a regularization, such as a photon-number cutoff, to enable the definition of ensembles of random unitaries on effective subspaces.
In this work, we consider the task of performing #shadowtomography of a logical subsystem defined via the Gottesman-Kitaev-Preskill (#GKP) error correcting code. In particular, we construct a logical shadow tomography protocol via twirling of CV-POVMs by displacement operators and Gaussian unitaries. In the special case of heterodyne measurement, the shadow tomography protocol yields a probabilistic decomposition of any input state into Gaussian states that simulate the encoded logical information of the input relative to a fixed GKP code and we prove bounds on the Gaussian compressibility of states in this setting.
For photon-parity measurements, logical GKP shadow tomography is equivalent to a #Wigner sampling protocol for which we develop the appropriate sampling schemes and finally, using the existence of a Haar measure over symplectic lattices, we derive a Wigner sampling scheme via random GKP codes.
This protocol establishes, via explicit sample complexity bounds, how Wigner samples of any input state from random points relative to a random GKP codes can be used to estimate any sufficiently bounded observable on CV space.

We just submitted interesting #DTI data on #AbsolutePitch that consider this exceptional skill as a #ContinuousVariable. Not like previous studies that categorically separated AP and NAP based on a test participants completed at home.
So, I currently have my wind direction variable set up as an actual direction (i.e. NNW or SE) in my model, but I have the wind direction in degrees (in 10s) and want to use this in my analysis so that my variable is continuous/numerical rather than categorical/as a factor.
Real life 'stats'. When you hear someone sneeze, do you say 'Gesundheit/God bless you'? #categoricalvariable If yes, at what distance from the 'sneezer' do you not? #continuousvariable
