Non-Hermitian Computers Need No Complex Numbers
Qi Zhang
In traditional quantum computing, it has been established that real quantum computation augmented with non-Clifford gates is as powerful as universal quantum computation. Here we i…
Physics and computation: An insight from non-Hermitian quantum computing
Qi Zhang, Biao Wu
We elucidate the profound connection between physics and computation by proposing and examining the model of the non-Hermitian quantum computer (NQC). In addition to conventional q…
Quantum-enhanced satellite image classification
Qi Zhang, Anton Simen, Carlos Flores-Garrigós +7
We demonstrate the application of a quantum feature extraction method to enhance multi-class image classification for space applications. By harnessing the dynamics of many-body sp…
Reversing Heat Flow by Coherence in a Multipartite Quantum System
Keyi Huang, Qi Zhang, Xiangjing Liu +12
The second law of thermodynamics dictates that heat flows spontaneously from a high-temperature entity to a lower-temperature one. Yet, recent advances have demonstrated that quant…
The Power of Lorentz Quantum Computer
Qi Zhang, Biao Wu
We demonstrate the superior capabilities of the recently proposed Lorentz quantum computer (LQC) compared to conventional quantum computers. We introduce an associated computationa…
