Advances in Theoretical and Mathematical Physics, 2009 The problem of quantizing a symplectic manifold (M, ) can be formulated in terms of the A-model of a complexification of M. This leads to an interesting new perspective on quantization. From this point of view, the Hilbert space obtained by quantization of (M, ) is the space of (Bcc,B') strings, where Bcc and B' are two A-branes; B' is an ordinary ...

QDrop: Randomly Dropping Quantization for Extremely Low-bit Post-Training Quantization [PDF]
International Conference on Learning Representations, 2022 Recently, post-training quantization (PTQ) has driven much attention to produce efficient neural networks without long-time retraining. Despite its low cost, current PTQ works tend to fail under the extremely low-bit setting.

Nuclear Physics B, 1998 We present a superfield formulation of the quantization program for theories with first class constraints. An exact operator formulation is given, and we show how to set up a phase-space path integral entirely in terms of superfields. BRST transformations and canonical transformations enter on equal footing, and they allow us to establish a superspace ...

Nuclear Physics B - Proceedings Supplements, 2000 Starting from a functional formulation of classical mechanics, we show how to perform its quantization by freezing to zero two Grassmannian partners of time.

From geometric quantization to Moyal quantization [PDF]
Journal of Mathematical Physics, 1995 It is shown how the Moyal product of phase-space functions, and the Weyl correspondence between symbols and operator kernels, may be obtained directly using the procedures of geometric quantization, applied to the symplectic groupoid constructed by ‘‘doubling’’ the phase space.

Dissipation and quantization [PDF]
Physics Letters A, 2001 We show that the dissipation term in the Hamiltonian for a couple of classical damped-amplified oscillators manifests itself as a geometric phase and is actually responsible for the appearance of the zero point energy in the quantum spectrum of the 1D linear harmonic oscillator. We also discuss the thermodynamical features of the system.

Least squares quantization in PCM
IEEE Transactions on Information Theory, 1982 It has long been realized that in pulse-code modulation (PCM), with a given ensemble of signals to handle, the quantum values should be spaced more closely in the voltage regions where the signal amplitude is more likely to fall.

Weyl Quantization from geometric quantization [PDF]
AIP Conference Proceedings, 2008 A. Weinstein has conjectured a nice looking formula for a deformed product of functions on a hermitian symmetric space of non-compact type. We derive such a formula for symmetric symplectic spaces using ideas from geometric quantization and prequantization of symplectic groupoids.

ZeroQ: A Novel Zero Shot Quantization Framework [PDF]
Computer Vision and Pattern Recognition, 2020 Quantization is a promising approach for reducing the inference time and memory footprint of neural networks. However, most existing quantization methods require access to the original training dataset for retraining during quantization.
