Ignacio Cirac discusses quantum information and the path from theoretical ideas to useful quantum technologies. Topics include trapped-ion qubits, quantum simulation, Rydberg-atom approaches and the choices facing hardware developers. The conversation also considers expectations, industrial development and the European quantum research community.

Quantum information methods can improve the design of precision sensors. This talk first uses error correction to distinguish suppressible noise from disturbances inseparable from the signal, extending from individual qubits to collective and distributed sensing. It then applies ideas from tomography, certification and purification to estimating several parameters at once. The proposed measurement protocols address incompatible observables while seeking practical implementation and near-optimal sensitivity.

Jadwiga Wilkens of Johannes Kepler University Linz presents gate-set-shadow methods for characterising noise on a 36-qubit superconducting processor. The seminar examines reconstructed noise channels, correlated errors and cross-talk, including limitations of standard noise models. The confirmed Quantum Information seminar is scheduled for 9 September 2026, from 11:00 to 12:30 Toronto time in Perimeter Institute's Bob Room.

Daniel Harlow discusses what attempts to reconcile gravity and quantum mechanics reveal about quantum theory itself. The conversation follows black-hole radiation, information loss, the wave function of the universe, the AdS/CFT correspondence and quantum information. It then connects these developments to quantum cosmology and questions about the structure of quantum mechanics.

Mete Atatüre examines semiconductor quantum dots as interfaces between photons, electron spins and ensembles of nuclear spins. Optical control can turn the nuclear environment from a source of noise into a useful quantum system. The seminar follows this progression through collective nuclear states toward a register capable of storing quantum information.

Spin-one-half systems provide a common mathematical language for stationary qubits. This introductory lecture explains how quantum information can be represented, manipulated and measured using atomic energy levels or defects in solids. It connects the formalism to basic quantum-processor components and to magnetic-field sensors based on controlled spins.

Adina Goldberg discusses the mathematical study of quantum information and how it differs from classical information encoded in bits. Her perspective on the meaning carried by relationships and arrows connects her research with her career path. The conversation was recorded during a quantum-information research programme at the Isaac Newton Institute.

Zijian Wang studies how dephasing affects Laughlin and Moore–Read quantum Hall states and their ability to store quantum information. Plasma analogies and field theory reveal two regimes separated by a critical filling: below it, finite noise causes a Berezinskii–Kosterlitz–Thouless transition and degrades the encoded memory; above it, memory survives until infinite noise. The critical filling is one quarter for Rényi-2 and lies between one quarter and one eighth in the replica limit. For Moore–Read states, the transition also governs whether non-Abelian fusion outcomes remain distinguishable.
