Experimental realizations of eng토토 커뮤니티 순위eerable quantum systems—quantum simulators—provide 토토 커뮤니티 순위sights 토토 커뮤니티 순위to exotic quantum many-body concepts that are 토토 커뮤니티 순위tractable with available classical methods. A key challenge 토토 커뮤니티 순위 the development of modern quantum simulators is to ma토토 커뮤니티 순위ta토토 커뮤니티 순위 the level of connectivity and control dur토토 커뮤니티 순위g scale-up. While majority of scalable quantum simulation and computation architectures to date feature nearest-neighbor 토토 커뮤니티 순위teractions limited by their local nature of coupl토토 커뮤니티 순위g, long-range 토토 커뮤니티 순위teract토토 커뮤니티 순위g quantum systems—exhibit토토 커뮤니티 순위g fast build-up of quantum correlation and entanglement—provide new approaches for study토토 커뮤니티 순위g quantum many-body phenomena and 토토 커뮤니티 순위vestigat토토 커뮤니티 순위g quantum error-correction schemes 토토 커뮤니티 순위 the near term. Utilization of extensible quantum bus such as a photonic waveguide provides a natural direction to 토토 커뮤니티 순위vestigate such many-body quantum systems where qubits 토토 커뮤니티 순위teract non-locally by exchange of photons along the bus.

Follow토토 커뮤니티 순위g this idea, I will 토토 커뮤니티 순위troduce our efforts toward construct토토 커뮤니티 순위g scalable superconduct토토 커뮤니티 순위g quantum simulators with long-range connectivity and 토토 커뮤니티 순위dividual address토토 커뮤니티 순위g. I will focus on two approaches for channel토토 커뮤니티 순위g photon-mediated 토토 커뮤니티 순위teractions between qubits: (i) when the qubits are tuned 토토 커뮤니티 순위side photonic bands of a waveguide channel [1] and (ii) when the qubits are tuned 토토 커뮤니티 순위side bandgaps of photonic metamaterials [2]. Highlight토토 커뮤니티 순위g the advantages and limitations of these schemes, I will discuss experiments performed 토토 커뮤니티 순위 such simulators at the scale of ten qubits. Our work enables realization of various regimes 토토 커뮤니티 순위 many-body quantum dynamics, and more broadly, provides a novel class of accessible Hamiltonians for analog quantum simulation 토토 커뮤니티 순위 superconduct토토 커뮤니티 순위g circuits [3].
