Abstract: A navigation system for a blind individual to guide the individual through a virtual environment, includes a transponder adapted to be carried by the individual, a tracking system for determining the position of said transponder within the virtual environment, and a feedback system coupled to said transponder to generate a non-visual sensory signal indicative of said position of said transponder. The transponder has a primary sensor direction that is aimed by the individual, and the non-visual sensory signal provides indications of virtual objects aligned with said primary sensor direction, whereby the individual may be guided to find or avoid virtual objects in said virtual environment.

Abstract: Devices and/or computer-implemented methods to facilitate a cross-resonance operation in a dispersive regime of a qubit frequency space are provided. According to an embodiment, a device can comprise a first qubit having a first operating frequency and a first anharmonicity. The device can further comprise a second qubit that couples to the first qubit to perform a cross-resonance operation. The second qubit having a second operating frequency and a second anharmonicity. A detuning between the first operating frequency and the second operating frequency is larger than the first anharmonicity and the second anharmonicity.
