Abstract: Aspects of the invention provide methods and systems for moving a plurality of moveable stages relative to a stator. The stator comprises a plurality of coils shaped to provide pluralities of coil trace groups where each coil trace group comprises a corresponding plurality of generally linearly elongated coil traces which extend across a stator tile. Each moveable stage comprises a plurality of magnet arrays. Methods and apparatus are provided for moving the moveable stages relative to the stator, where a magnet array from a first moveable stage and a magnet array from a second moveable stage both overlap a shared group of coil traces. For at least a portion of the time that the magnet arrays from the first and second moveable stages overlap the shared group of coil traces, currents are controllably driven in the shared coil trace group based on the positions of both the first and second moveable stages. The positions of the first and second moveable stages may be ascertained by feedback.

Abstract: Lipid-based vesicles, typically herein called transfection competent vesicles (TCVs), configured to safely and efficiently deliver DNA, RNA, other nucleic acid and protein cargoes into target cells. The safety and efficiency are each, and both, achieved in part by eliminating organic solvents such as ethanol and detergents such as sodium dodecyl sulfate from the TCV loading processes (i.e., inserting a cargo into the TCV), TCV storage processes, and/or TCV delivery processes. The cargoes can also comprise nucleic acids complexed with a protein, such as a ribonucleoprotein (RNP). The systems, compositions, devices and methods, etc., herein, in some embodiments, can provide empty TCVs that can if desired be loaded at the bench without use of specialized equipment.

Abstract: Aspects of the invention provide methods and systems for moving moveable stages relative to a stator. A stator is operationally divided into multiple stator tiles. The movement of the one or more moveable stages is controlled by a plurality of controllers (each assigned particular control responsibilities). A controller is provided for each stator sector, where each stator sector comprises a group of one or more stator tiles. Controllers from neighboring sectors share various information to facilitate controllable movement of one or more moveable stages relative to the stator.
Abstract: A modular quantum computer architecture is developed with a hierarchy of interactions that can scale to very large numbers of qubits. Local entangling quantum gates between qubit memories within a single modular register are accomplished using natural interactions between the qubits, and entanglement between separate modular registers is completed via a probabilistic photonic interface between qubits in different registers, even over large distances. This architecture is suitable for the implementation of complex quantum circuits utilizing the flexible connectivity provided by a reconfigurable photonic interconnect network. The subject architecture is made fault-tolerant which is a prerequisite for scalability.
