Quantum Optics

Invited Talk

Quantum mechanics lies at the heart of many fascinating phenomena in condensed matter physics. One prominent effect is superconductivity, where fermionic electrons pair up to form composite bosons. Their collective quantum coherence gives rise to superconductivity and closely related superfluid behavior.

Ultracold atoms provide a powerful platform for studying these phenomena on a...

19. Rydberg-Mediated Cooling of a GHz Bulk Acoustic Wave Mechanical Resonator

Quantum Optics

Contributed Talk

Rydberg atoms provide electric dipole–allowed transitions that span from optical to microwave frequencies, combining optical control with strong, tunable coupling to microwave-frequency solid-state systems. This makes them a powerful candidate for interfacing atomic ensembles with on-chip electromechanical devices. In this work, we study such an interface between Rydberg atoms and a...

109. Position-Dependent Entanglement-Assisted Quantum Walks with GHZ Coin State

Quantum Information & Computing

Contributed Talk

Quantum walks provide a powerful platform for exploring non-classical transport phenomena and for designing controllable quantum dynamics in discrete systems. Here, we investigate the transport properties of a one-dimensional discrete-time quantum walk driven by a three-qubit Greenberger–Horne–Zeilinger (GHZ) entangled coin state, focusing on the contrasting effects of position-dependent (PD)...

98. Dynamics of 40Ca+ Ions Confined in a Tapered Paul Trap

Manika Bhardwaj (Experimental Physics I, University of Kassel, Heinrich-Plett-Strasse 40, 34132 Kassel, Germany)

Atomic & Molecular Physics

Contributed Talk

When multiple harmonic oscillators are coupled, they exhibit normal modes, which can be either delocalized or localized. The delocalized modes are used to exchange information between qubits in a Paul trap for quantum information processing, while localized modes can be used for frequency-resolved addressing. In this work, we observe both delocalized and localized normal modes depending on...
