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…
Active Noise Reduction in Si/SiGe Gated Quantum Dots
Rajat Bharadwaj, Parvathy Gireesan, Harikrishnan Sundaresan +5
Solid-state quantum technologies such as quantum dot qubits and quantum electrical metrology circuits rely on quantum phenomena at ultra-low energies, making them highly sensitive…
