Abstract: Systems, methods, computer-readable media, and techniques disclosed herein provide for preparing a solution to a problem comprising a constraint on a non-classical computer, comprising: (a) providing a state preparation operation, wherein the state preparation operation comprises at least a portion of an implementation of the problem comprising the constraint on the non-classical computer, wherein the state preparation operation is configured to evolve a quantum register to a solution state; (b) applying a constraint detection operation, the constraint detection operation comprising entangling an ancilla qubit with a set of data qubits; and (c) measuring the ancilla qubit to determine whether a constraint of the problem is satisfied.

Abstract: A method of manufacturing a measuring wheel for wireline operations includes the step of machining a metal wheel to achieve a first outer radius. The metal wheel is positioned within a ceramic ring having an inner radius that exceeds the first outer radius by an amount in the range of 0.005 to 0.010 inches, defining a gap between the ceramic ring and the metal wheel. The gap is substantially filled with a suitable epoxy, and the epoxy is cured to adjoin the ceramic ring to the metal wheel. The perimeter of the ceramic ring is machined to achieve a second outer radius and a desirable surface finish and pattern.
