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 reactive target that can be operated by a BB gun, Airsoft gun, Slingshot.

A modular target having a support pole and a head. The head is preferably removable. The head is configured for removable attachment of a target. The head has a rail onto which a sleeve of a target is attached. The rail is preferably cylindrical. The target is configured with a sleeve that slides over the rail. Preferably a shooting face extends from the sleeve. Further, the shooting face is configured such that a moment arm allows the shooting face to hang at a 5-20 degree angle from vertical, with the preferred angle being 10 degrees. In a preferred embodiment the modular target utilizes a removably head configured with a neck that attaches to a vertical support pole. The vertical support pole preferably has a slide hammer attached that allows for easier placement of the target in the ground. Preferably the support pole has a fin that serves to resist rotation of the support pole when the target is hit by a projectile fired by a firearm.

A multipurpose shooting platform target and stand devised for use in training with large caliber, high, and hyper velocity weaponry includes a target plate dependable from a frame member by hooked engagement between a cylindrical member and a rearward mount. The rearward mount is disposed upon a reverse surface of the target plate. Engagement with the cylindrical member of the frame member effects orientation of the target plate under the influence of gravity to rest at an acute angle relative an underlying surface. Impact of ballistics against an obverse surface of the target plate effects movement of a lowermost edge of the target plate rearwards, and impacted rounds are readily deflected in controlled trajectories downwards towards the underlying surface without danger of ricochet in unpredictable patterns. Swing of the target plate signals impact of the obverse surface to a shooter.

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 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.
