Tunnel-rate controlled local heat distribution in mesoscopic circuits
Parvathy Gireesan, Umang Soni, Harikrishnan Sundaresan +2
Solid-state quantum technologies, including qubits and quantum metrology circuits, demand milli-Kelvin operation to preserve fragile quantum states from classical noise. While the…
Cascaded Four-Wave Mixing on Quantum Paraelectrics for On-chip Cryogenic Microcombs
Harikrishnan Sundaresan, Prasad Muragesh, Madhu Thalakulam
Here, we demonstrate an on-chip cryogenic microwave frequency-comb on a planar superconducting resonator fabricated on Strontium titanate(STO), a quantum paraelectric material. The…
Cryogenic microwave frequency combs based on quantum paraelectric superconducting resonators
Prasad Muragesh, Harikrishnan Sundaresan, Madhu Thalakulam
A frequency comb, known for its precision as an "optical ruler", features an evenly spaced spectral pattern. While these combs are vital in photonic quantum technologies, their mic…
