Physicists at TU Wien clarify a long-lasting theoretical debate about the vacuum states of cavity QED. © TU Wien Quantum electrodynamics (QED) is the fundamental theory of electromagnetism, which also describes how atoms, [...]

In superconducting circuits, superinductors are employed to suppress charge fluctuations and increase zero-point voltage, enabling features for hardware-protected qubits, metrological standards, and strongly coupled hybrid devices. Conventionally these devices are based on kinetic [...]

ERC Synergy Grants for Thomas Pichler and Markus Aspelmeyer. The physicist Thomas Pichler and his international team will receive an ERC Synergy Grant of 14 million Euros to build a new electron nano-spectrometer [...]

Quantum physicists of IQOQI-Vienna and the University of Vienna present in the journal PNAS a new method to produce high-dimensionally entangled photon pairs. These systems can be the base for robust communication protocols [...]
