A theory addressing the quantum measurement problem: collapse occurs when the entangling speed reaches a threshold
Sang Jae Yun
To resolve the quantum measurement problem, we propose an objective collapse theory in which both the wavefunction and the process of collapse are regarded as ontologically objecti…
Superconducting qubit without Josephson junctions manipulated by the orbital angular momentum of light
Sang Jae Yun
Conventional superconducting qubits have used Josephson junctions as an essential part to provide anharmonicity for well-separated energy-level spacings. However, because a superco…
Molecular quantum rotors in gyroscopic motion with a nonspreading rotational wavepacket
Sang Jae Yun, Chang Hee Nam
We provide a way of generating and observing molecular quantum gyroscopic motion that resembles gyroscopic motion of classical rotors. After producing a nonspreading rotational wav…
Quantum Computation with Rotational States of Nonpolar Ionic Molecules
Sang Jae Yun, Chang Hee Nam
We propose a quantum computer architecture which is robust against decoherence and scalable. As a qubit, we adopt rotational states of a nonpolar ionic molecule trapped in an ion-t…
An analytic formula determining quantum pointer basis and its application to a flying bullet
Sang Jae Yun
We propose a general scheme determining the quantum pointer basis of a macroscopic object interacting with environment. Unlike the decoherence program, our pointer basis does not r…
Ising interaction between two qubits composed of the highest magnetic quantum number states through magnetic dipole-dipole interaction
Sang Jae Yun, Jaewan Kim, Chang Hee Nam
In quantum information processing, one of the most useful interaction between qubits is the Ising type interaction. We propose a scheme to implement the exact Ising interaction thr…
