In this work, we derive analytic formulae that determine the effect of error mechanisms on one- and two-qubit gates in trapped ions electrons. First, analyze, expressions for, driving field inhomogeneities one-qubit gate fidelities. Second, for errors, including static motional frequency shifts, trap anharmonicities, inhomogeneities, heating, dephasing. We show that, small each our infidelity converges to its respective numerical simulation; shows are sufficient determining budgets...
We demonstrate trapping of electrons in a millimeter-sized quadrupole Paul trap driven at 1.6 GHz room-temperature ultrahigh vacuum setup. Cold are introduced into the by ionization atomic calcium via Rydberg states and stay confined microwave static electric fields for several tens milliseconds. A fraction these remain trapped longer show no measurable loss measurement times up to second. Electronic excitation motion reveals secular frequencies that can be tuned over range hundreds MHz....
With the widespread application of low-temperature fuel cells in aviation industry, power cell systems is gradually increasing, leading to an increasing demand for heat dissipation thermal management systems. Compact exchangers play a crucial role achieving within these systems, with performance fins being particularly critical as it directly impacts system's and safety. Therefore, necessary study effects fins. In this study, three types fin combinations were established: double...
Listening and speaking are tied to human experiences of closeness trust. As voice interfaces gain mainstream popularity, we ask: is our relationship with technology that speaks us fundamentally different from use read type? In particular, will disclose more about ourselves computers speak listen answer? We examine this question through a controlled experiment where conversational agent asked participants closeness-generating questions common in social psychology either text-based or...
We investigate the feasibility of using electrons in a linear Paul trap as qubits future quantum computer. discuss necessary experimental steps to realize such device through concrete design proposal, including trapping, cooling, electronic detection, spin readout and single multi-qubit gate operations. Numeric simulations indicate that two-qubit Bell-state fidelities order 99.99% can be achieved assuming reasonable parameters.
Trapped-ion applications, such as in quantum information, precision measurements, optical clocks, and mass spectrometry, rely on specialized high-performance ion traps. The latter applications typically employ traditional machining to customize macroscopic 3D Paul traps, while information processing experiments usually photo-lithographic techniques miniaturize the traps meet scalability requirements. Using photolithography, however, it is challenging fabricate complex three-dimensional...
