Described is a scalable quantum computer that includes at least two classical to quantum interface devices, with each being connected to a distinct quantum processing unit (QPU). An Einstein-Podolsky-Rosen pair generator (EPRPG) is included for generating an entangled Einstein-Podolsky-Rosen pair that is sent to the QPUs. Each QPU is quantumly connected with the EPRPG and is configured to receive a mobile qubit from the EPRPG and perform a sequence of operations such that the mobile qubit interacts with a source qubit when a teleportation algorithm is initiated, leaving a second mobile qubit in the original quantum state of the source qubit.

Scalable quantum computer

The present invention provides a method to construct stable, high-order explicit discretization for the wave equation based on the discretization of the evolution formula. The present invention provides independent computation of discretization in one, two, or more spaces for bulk propagation, near boundaries propagation, and discretization of a projection operator to enforce boundary conditions. More specifically, the method includes an act of discretizing propagation operators Lby using an identity that is derived using central differencing in time. The method also includes an act of providing a high-order discretization of a boundary projection operator that enforces boundary conditions independent of the discretization of the propagation operators L. Additionally, the method includes an act of alternating an application of a discretization of an evolution formula having a spatial filtering operator Lwith a boundary projection operation for stepping forward in time to determine wave propagation in the media.

System and a method for numerical simulation of wave propagation in homogeneous media

A computer program product, an apparatus, and a method for modeling equivalent surface sources on a closed, arbitrarily shaped object that result from the imposition of an arbitrary time-harmonic incident field (e.g., a radar wave) are provided. An object divided into by a plurality of patchesand parameters for the incident field and the properties of the objectare provided to the system. Next, the system produces a discretized representation of a well-conditioned boundary integral equation in the form of a well-conditioned matrix equation, modeling the interaction between the incident field and the object. The well-conditioned linear system is solved numerically to determine equivalent surface sources on the object. The equivalent sources may then be used to determine electromagnetic fields resulting therefrom. The invention provides improved computational efficiency as well as increased modeling accuracy by effectively reducing the numerical precision necessary.
