Floquet engineering, i.e. driving the system with periodic Hamiltonians, notonly provides great flexibility in analog quantum simulation, but also supportsphase structures of great richness. It has been proposed that Floquet systemscan support a discrete time-translation symmetry (TTS) broken phase, dubbed thediscrete time crystal (DTC). This proposal, as well as the exotic phase, hasattracted tremendous interest among the community of quantum simulation. Herewe report the observation of the DTC in an one-dimensional superconductingqubit chain. We experimentally realize long-time stroboscopic quantum dynamicsof a periodically driven spin system consisting of 8 transmon qubits, andobtain a lifetime of the DTC order limited by the coherence time of theunderlying physical platform. We also explore the crossover between thediscrete TTS broken and unbroken phases via various physical signatures. Ourwork extends the usage of superconducting circuit systems in quantum simulationof many-body physics, and provides an experimental tool for investigatingnon-equilibrium dynamics and phase structures.
