Abstract: A system for providing a visual tour guide including driving instruction may include a media database including instructional videos and traditional tour guide and map files. The instructional videos may also include videos generated by a driver in a foreign country with a 360 degree camera. The user may change the field of view to emulate the driver turning their head. Graphics representative of traffic signs and testing material may be overlaid over the video. The system may provide a live stream driving experience. The user provides a desired destination, which is sent to a driver near the destination. The driver may have a 360 degree camera mounted to their vehicle, and the system can transmit the live stream video to the driver. The system may also include a driving environment incorporating VR and/or AR aspects, which may be based on real world traffic or completely simulated.

Abstract: Quantum circuits and methods load N=2n classical bits into an entangled quantum output state using a gate depth of order O(n). Loading is accomplished by dividing the 2n input bits into data words and entangling these data words using ancilla qubits. The output of the circuit consists of one data word and one or several index qubits, drawn from the ancilla, to select between the input data words. Entanglement of the data words is performed in a single time slice (i.e. with a gate depth of 1), while the number of sequential gates needed to produce the appropriate pre-entanglement quantum state in the ancilla, and to disentangle the non-output ancilla, has the desired order O(n). Also disclosed is a circuit for disentangling qubits used to store non-output data words during processing.
