Suleymanzade builds hybrid quantum systems that couple Rydberg atoms, superconducting circuits, and nanophotonics to create new quantum interfaces and entanglement resources for quantum networking, communication, and sensing, following earlier work on silicon-vacancy diamond quantum networks. The lab is actively recruiting postdocs.

Vedral leads the Quantum Devices and Biosystems group, working at the intersection of quantum information and biology. Research themes include: (1) quantum effects in living systems — studying entanglement and non-classicality in biological organisms such as tardigrades placed in quantum superposition inside superconducting qubits; (2) BMV-type experiments to test whether gravity is a quantum field by measuring gravity-mediated entanglement between two massive quantum superpositions; (3) theoretical frameworks for witnessing quantum effects in complex macroscopic systems. While primarily theoretical, the group actively collaborates with and directs experiments. Borderline: included as the group formally aims for experimental demonstrations of quantum effects in living systems.

Xu leads the Experimental Quantum Engineering group with a joint ETH–PSI appointment. Research directions: (1) Superconducting circuit quantum sensing — using qubits-as-sensors for detecting weak microwave signals beyond standard quantum limits, quantum non-demolition readout of photon fields; (2) Quantum error correction enabled sensing — integrating bosonic codes (cat qubits, binomial codes) into sensing protocols; (3) Quantum acoustics — coupling superconducting qubits to surface acoustic wave (SAW) resonators for hybrid quantum sensing; (4) Novel quantum hardware at PSI — leveraging PSI's infrastructure for cryogenic device fabrication and testing. Connected to the ETH–PSI Quantum Computing Hub.

Yang works on the systems-level physics of silicon spin qubits: operating qubits at elevated temperatures (above one kelvin, where cryo-CMOS control electronics can be co-integrated), valley and spin-orbit engineering, and the electrical control of spin qubits without micromagnets. The 'hot qubit' programme in particular is an engineering argument about where the classical/quantum boundary should sit in a real machine. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — raising the operating temperature of a spin sensor while preserving coherence is the same trade a pT/sqrt(Hz) NV ensemble makes implicitly by working at room temperature; Yang's work is the silicon community's attempt to buy back some of that convenience. Borderline inclusion — this is quantum computing rather than sensing — retained under the inclusive rubric.

Develops rare-earth-ion-doped crystal platforms for quantum internet hardware. Directions: (1) Er3+-doped crystal quantum memories with >1 ms coherence time in nanophotonic waveguides; (2) microwave-to-optical quantum transduction using Er spins coupled to superconducting resonators; (3) photon-number-resolving detectors for quantum communication; (4) integrated rare-earth nanophotonic circuits on thin-film LiNbO3. Key goal: scalable room-temperature-compatible quantum repeater nodes.
