alternative to Quantum Fourier Transform with efficient neural net classical post-processing
Kaiming Bian, Zujin Wen, Oscar Dahlsten
The Quantum Fourier Transform (QFT) is required by hidden subgroup problem (HSP) algorithms, including Shor's algorithm for factoring. The circuit depth of the QFT remains challeng…

Channel Superposition Mitigates Photon Loss Errors in Quantum Illumination
Fei Li, Xiao-Wei Li, Oscar Dahlsten
In quantum illumination, the probe photon is entangled with an ancilla photon, and both are jointly measured at the end. The entanglement between the probe and ancilla photons enha…

Quantum Sinusoidal Neural Networks
Zujin Wen, Jin-Long Huang, Oscar Dahlsten
We design a quantum version of neural networks with sinusoidal activation functions and compare its performance to the classical case. We create a general quantum sine circuit impl…
