Reservoir-Engineered Low-Threshold Quantum Energy Storage
Borhan Ahmadi, André H. A. Malavazi, PaweŠMazurek +2
Fast charging of quantum batteries requires amplification of the energy transferred to a storage mode without uncontrolled gain or phenomenological non-Hermitian dynamics. Inspired…
Topological Polarization Beam Splitter with Polarization-Selective Edge States
Shirin Afzal, Amesh Kahloon, Shabir Barzanjeh
The realization of on-chip polarization beam splitters robust to fabrication imperfections remains a key challenge for polarization-sensitive photonic integration. We demonstrate a…
Hybridized-Mode Parametric Amplifier in Kinetic-Inductance Circuits
Danial Davoudi, Abdul Mohamed, Shabir Barzanjeh
Parametric amplification is essential for quantum measurement, enabling the amplification of weak microwave signals with minimal added noise. While Josephson-junction-based amplifi…
Quantum Optical Techniques for Biomedical Imaging
Vahid Salari, Yingwen Zhang, Sepideh Ahmadi +7
Quantum imaging is emerging as a transformative approach for biomedical applications, applying nonclassical properties of light, such as entanglement, squeezing, and quantum correl…
Harnessing Environmental Noise for Quantum Energy Storage
Borhan Ahmadi, Aravinth Balaji Ravichandran, PaweÅ Mazurek +2
Quantum hardware increasingly relies on energy reserves that can later be converted into useful work; yet, most battery-like proposals demand coherent drives or engineered non-equi…
Nonreciprocity in Quantum Technology
Shabir Barzanjeh, André Xuereb, Andrea Alù +4
Nonreciprocity-the ability to transmit signals in one direction while blocking them in the reverse-has become a powerful resource in quantum technologies, enabling directional ampl…
