Abstract: Autonomous modular robots and methods of use are disclosed herein. An example system includes a first assembly includes a first controller having a first processor that causes a first assembly support to translate along a first axis and align with a container placed on the first assembly support which is connected to a third assembly. The third assembly is configured to release a lid when the container has been engaged with the lid. The lid and container form a second assembly that includes a second processor and a second sensor assembly located in the lid. A transfer assembly can transfer an object into and out of the container. The first processor can determine a position and orientation of a delivery platform, planned movement and position of the second assembly, and planned operations of the transfer assembly in order to deliver a package to the delivery platform.

Abstract: A method for quantum state transfer includes iteratively expanding an initial quantum state from an initial qudit, of a plurality of qudits, over a sequence of expanding domains. For each iteration, a quantum circuit is applied to the qudits belonging to a respective domain of the sequence. The quantum circuit transforms the qudits of the respective domain into an intermediate quantum state that includes a W state formed with the qudits of the respective domain. The last iteration generates a maximally expanded state. The method may also include iteratively compressing the maximally expanded state according to a sequence of contacting domains. After compressing, a final qudit, of the plurality of qudits, is in a final quantum state that approximates the initial quantum state.
