In Other Words

Demonstrating that a single photon from a semiconductor quantum dot can be quadrature-squeezed, its electric-field noise dropping below vacuum, ‘below the level of nothingness’, a property textbooks said was too hard to observe.

Key Takeaways

Professor at University of Cambridge studying light–matter interaction at the quantum level in semiconductors, diamond and 2D materials, for quantum networks and quantum sensors.
Adding the electron spin to the single photon opens a new dimension: photon–spin entanglement lets you distribute entanglement between distant nodes and use quantum dots as quantum repeaters (no amplifiers, per no-cloning).
No single material wins: quantum dots are the best single-photon source, diamond the best spin/memory, hBN is temperature-agnostic (good for space).
Nanodiamond NV-centre sensors can go inside living cells (even C. elegans) to non-destructively map magnetic field, pH, temperature and viscosity at the nanoscale, a surprise life-sciences application.
Career: Turkey → Boston → ETH Zurich → Cambridge; champions researcher mobility. Wishes: keep the same calibre of team, unallocated thinking time, and steady baseline funding.
