Apparatus and methods for removing leakage from a qubit. In one aspect, an apparatus includes one or more qubits, wherein each qubit facilitates occupation of at least one of a plurality of qubit levels, the qubit levels including two computational levels and one or more non-computational levels that are each higher than the computational levels, wherein the qubit facilitates transitions between qubit levels associated with a corresponding transition frequency; a cavity, wherein the cavity defines a cavity frequency; one or more couplers coupling each qubit to the cavity; one or more couplers coupling the cavity to an environment external to the one or more qubits and the cavity; a frequency controller that controls the frequency of each qubit such that, for each qubit, the frequency of the qubit is adjusted relative to the cavity frequency such that a population of a non-computational level is transferred to the cavity.

A laser targeting apparatus rests on a surface and moves, such as by vibrating, wobbling, or shaking, when struck by laser light of sufficient intensity. The apparatus is designed not to fall over, so a user does not have to move to the apparatus and pick it up after a strike. The apparatus has a body that includes a structure, which is preferably one or more printed circuit boards including light sensors, for detecting strikes of laser light, and a motor. When a strike of laser light is detected, power is provided to the motor, which vibrates and causes the apparatus to move.

A flying object water game by which an object is thrown or tossed at a framework on which water emitting targets reside. A target framework includes one or more detachable water emitting targets. A first team defends the framework while a second team throws or tosses, from a predetermined distance, a flying object at the target framework and associated water emitting targets with the objective to hit and detach one or more targets from the framework.
