Quantum Detectors introduces the Quantum C100. Born from discussions in the Cryo-EM field, this detector is designed as the ideal detector for performance at 100keV. View Product V2F100 The V2F100 allows users t
Central elements of quantum integrated photonics are quantum emitters, memories, detectors, and reconfigurable photonic circuits. In particular, integrated detectors not only offer optical readout but, when interfaced with reconfigurable circuits, allow feedback and adaptive control, crucial for ...
Thirty years after it was first proposed, quantum teleportation remains one of the most important protocols in quantum information and quantum technologies, enabling the nonlocal transmission of an unknown quantum state. Quantum teleportation can be
Assuming that the quantum state of SPDC photon pairs is given by Eq. (59), the near-field correlations are governed by the profile of the pump beam W(ρ) and the Fourier transform of the phase matching function: Γ(ρ)=F{γ(q)}. Typically, Γ(ρ) is much narrower than W(ρ) at...
To do this, Bob enlarges the Hilbert space by entangling the quantum state of the channel particle via a unitary transformation with the states of two ancilla particles that he introduces. One particle is associated with a Hilbert space spanned by two eigenstates, |dx〉 and |dz〉, of a ...
It’s an attractive technology because an attacker sniffing the key exchange changes the quantum state of the photons involved. All eavesdroppers can be detected because of this fundamental principal of quantum mechanics. We’ve seen theoretical side-channel attacks on the hardware being used, but ...

Any initial state that does not lie in an eigenspace of the operator 𝐵̂ defines an indefinite COoE. Figure 1. A set-up by which to measure the causal order of two events that correspond to detections at detectors 1 and 2. We employ Equation (15), to compute the matrix elements ...
Solid state detectors rely on the interaction of energy with matter.The absorbed energy from for example, a charged particle, a photon or a phononis degraded and shared among a number of electronic, thermal and/or magneticexcitations. Quantum Giaever detectors are usually called super-conducting ...
4.3 Single photon detectors Due to the large downlink transmission losses, achieving a high enough entangled pair coincidence rate between the OGS and the CubeSat requires a high pair-production rate onboard CQuCoM, consequently we need high-speed single photon counters. Si-APDs are baselined for...
