varvec phi psi model for electrodynamics in dielectric media exact quantisation in the Heisenberg Representation
European Physical Journal C, 2016Co-Authors: Francesco Belgiorno, Sergio L. Cacciatori, Francesco Dalla Piazza, M. DoronzoAbstract:We investigate the quantisation in the Heisenberg Representation of a model which represents a simplification of the Hopfield model for dielectric media, where the electromagnetic field is replaced by a scalar field \(\phi \) and the role of the polarisation field is played by a further scalar field \(\psi \). The model, which is quadratic in the fields, is still characterised by a non-trivial physical content, as the physical particles correspond to the polaritons of the standard Hopfield model of condensed matter physics. Causality is also taken into account and a discussion of the standard interaction Representation is also considered.

Exact quantisation of the relativistic Hopfield model
Annals of Physics, 2016Co-Authors: Francesco Belgiorno, Sergio L. Cacciatori, F. Dalla Piazza, M. DoronzoAbstract:Abstract We investigate the quantisation in the Heisenberg Representation of a relativistically covariant version of the Hopfield model for dielectric media, which entails the interaction of the quantum electromagnetic field with the matter dipole fields, represented by a mesoscopic polarisation field. A full quantisation of the model is provided in a covariant gauge, with the aim of maintaining explicit relativistic covariance. Breaking of the Lorentz invariance due to the intrinsic presence in the model of a preferred reference frame is also taken into account. Relativistic covariance forces us to deal with the unphysical (scalar and longitudinal) components of the fields, furthermore it introduces, in a more tricky form, the well-known dipole ghost of standard QED in a covariant gauge. In order to correctly dispose of this contribution, we implement a generalised Lautrup trick. Furthermore, causality and the relation of the model with the Wightman axioms are also discussed.

An FPGA-based quantum circuit emulation framework using Heisenberg Representation
International Journal of Quantum Information, 2018Co-Authors: Y. H. Lee, M. Khalil-hani, M. N. MarsonoAbstract:While physical realization of practical large-scale quantum computers is still ongoing, theoretical research of quantum computing applications is facilitated on classical computing platforms through simulation and emulation methods. Nevertheless, the exponential increase in resource requirement with the increase in the number of qubits is an inherent issue in classical modeling of quantum systems. In the effort to alleviate the critical scalability issue in existing FPGA emulation works, a novel FPGA-based quantum circuit emulation framework based on Heisenberg Representation is proposed in this paper. Unlike previous works that are restricted to the emulations of quantum circuits of small qubit sizes, the proposed FPGA emulation framework can scale-up to 120-qubit on Altera Stratix IV FPGA for the stabilizer circuit case study while providing notable speed-up over the equivalent simulation model.

Improved quantum circuit modelling based on Heisenberg Representation
Quantum Information Processing, 2018Co-Authors: M. Khalil-hani, M. N. MarsonoAbstract:Heisenberg model allows a more compact Representation of certain quantum states and enables efficient modelling of stabilizer gates operation and single-qubit measurement in computational basis on classical computers. Since generic quantum circuit modelling appears intractable on classical computers, the Heisenberg Representation that makes the modelling process at least practical for certain circuits is crucial. This paper proposes efficient algorithms to facilitate accurate global phase maintenance for both stabilizer and non-stabilizer gates application that play a vital role in the stabilizer frames data structure, which is based on the Heisenberg Representation. The proposed algorithms are critical as maintaining global phase involves compute-intensive operations that are necessary for the modelling of each quantum gate. In addition, the proposed work overcomes the limitations of prior work where the phase factors due to non-stabilizer gates application was not taken into consideration. The verification of the proposed algorithms is made against the golden reference model that is constructed based on the conventional state vector approach.
