The dynamics of quantum information in strongly interacting systems, known as quantum information scrambling, has recently become a common thread in our understanding of black holes, transport in exotic non-Fermi liquids, and many-body analogs of quantum chaos. To date, verified experimental implementations of scrambling have focused on systems composed of two-level qubits. Higher-dimensional quantum systems, however, may exhibit different scrambling modalities and are predicted to saturate conjectured speed limits on the rate of quantum information scrambling. We take the first steps toward accessing such phenomena, by realizing a quantum processor based on superconducting qutrits (three-level quantum systems). We demonstrate the implementation of universal two-qutrit scrambling operations and embed them in a five-qutrit quantum teleportation protocol. Measured teleportation fidelities $F_{\mathrm{avg}}=0.568\pm 0.001$ confirm the presence of scrambling even in the presence of experimental imperfections and decoherence. Our teleportation protocol, which connects to recent proposals for studying traversable wormholes in the laboratory, demonstrates how quantum technology that encodes information in higher-dimensional systems can exploit a larger and more connected state space to achieve the resource efficient encoding of complex quantum circuits.

超导Qutrit处理器上的量子信息加扰

强相互作用系统中的量子信息动力学，称为量子信息加扰在我们对黑洞，异质非费米液体中的传输以及量子混沌的多体类似物的理解中，，成为最近的共同话题。迄今为止，经过验证的加扰实验实现方式都集中在由两级量子位组成的系统上。然而，高维量子系统可能表现出不同的加扰形式，并被预测为对量子信息加扰速率的推测速度极限将达到饱和。我们通过实现基于超导量子态（三级量子系统）的量子处理器，迈出了访问此类现象的第一步。我们演示了通用的二重扰码加扰操作的实现，并将其嵌入到五重量子量子隐形传态协议中。测得的传送保真度$F_{\mathrm{平均}}=0.568\pm 0.001$即使存在实验缺陷和退相干，也要确认是否存在加扰。我们的传送协议与最近在实验室研究可穿越的虫洞的提议相联系，证明了在高维系统中对信息进行编码的量子技术如何能够利用更大且连接更多的状态空间来实现复杂量子电路的资源高效编码。
