Quantum Sensing and Information

The banner image shows a single-molecule quantum sensor on a scanning probe tip that can detect electric and magnetic fields with sub-atomic spatial resolution.

About

We use scanning probe microscopes (SPM) in combination with electron spin resonance (ESR) to fabricate and utilize artificial nanostructures with custom-designed quantum states on surfaces and scanning probe tips for atomic-scale quantum information, sensing, and simulation.

Research Topics

  • Coherent control of individual spins
  • Atomic-scale quantum sensing
  • Analog quantum simulation on surfaces
  • Millikelvin STM with magnetic cooling

Research

a

Coherent control of individual spins

In search of new architectures for quantum information processing, we study spin qubits using scanning probe microscopy in combination with electron spin resonance.

a

Atomic-scale quantum sensing

We use the manipulation capabilities of scanning probe microscopes to fabricate molecular quantum sensors on the probe tips to detect the tiny electric and magnetic fields of quantum systems at the atomic level.

a

Analog quantum simulation on surfaces

We study interacting many-body quantum systems using standard spectroscopic detection schemes and by constructing controllable quantum systems of single atoms and molecules on surfaces as a platform for the analog simulation of the many-body systems.

a

Millikelvin STM with Magnetic Cooling

We have recently developed an ultra-high vacuum scanning tunnelling microscope that reaches a base temperature of 0.03 Kelvin. It employs adiabatic demagnetisation refrigeration (ADR).
