Real-space spectral functions of three-dimensional billion-size topological non-Hermitian matter with tensor networks
Yitao Sun, Jose L. Lado, Guangze Chen
Non-Hermitian systems host unconventional topological phenomena, while real-space spectral calculations in three dimensions remain computationally challenging. Here, we develop a t…
Controlled-Z gates with giant atoms in structured waveguides
Walter Rieck, Ariadna Soro, Anton Frisk Kockum +1
Giant atoms are quantum emitters coupled to waveguides at multiple, spatially separated points, enabling interference effects that fundamentally change their light-matter interacti…
Doublon bound states in the continuum through giant atoms
Walter Rieck, Anton Frisk Kockum, Guangze Chen
Bound states in the continuum (BICs) are spatially localized modes embedded in the spectrum of extended states, typically stabilized by symmetry or interference. While extensively…
Efficient three-qubit gates with giant atoms
Guangze Chen, Anton Frisk Kockum
Three-qubit gates are highly beneficial operations in quantum computing, enabling compact implementations of quantum algorithms and efficient generation of multipartite entangled s…
Scalable quantum simulator with an extended gate set in giant atoms
Guangze Chen, Anton Frisk Kockum
Quantum computation and quantum simulation require a versatile gate set to optimize circuit compilation for practical applications. However, existing platforms are often limited to…
Simulating open quantum systems with giant atoms
Guangze Chen, Anton Frisk Kockum
Open quantum many-body systems are of both fundamental and applicational interest. However, it remains an open challenge to simulate and solve such systems, both with state-of-the-…
