New SP3 Paper Proposes That Quantum Computation Operates Through Organized Conditioning of a Physical Medium Present ...

3D spatial tomography estimates the 3D structure of a subject from images taken from multiple directions. On the other hand, newly developed phase-space tomography estimates the plasma phase-space ...

Quantum Space has acquired Phase Four’s multi-mode propulsion assets to boost its capability to deliver highly maneuverable, persistent and cost-efficient platforms for national security, civil and ...

Phase Four says it has built and tested a next-generation radio-frequency thruster for spacecraft that equals the performance of a Hall-effect thruster. The achievement, demonstrated over several ...
