An ion trap is a combination of electric and/or magnetic fields used to capture charged particles — known as ions — often in a system isolated from an external environment. Atomic and molecular ion traps have a number of applications in physics and chemistry such as precision mass spectrometry, … Meer weergeven A charged particle, such as an ion, feels a force from an electric field. As a consequence of Earnshaw's theorem, it is not possible to confine an ion in an electrostatic field. However, physicists have … Meer weergeven An ion trap mass spectrometer may incorporate a Penning trap (Fourier-transform ion cyclotron resonance), Paul trap or the Kingdon trap. The Orbitrap, introduced … Meer weergeven Ion traps were used in television receivers prior to the introduction of aluminized CRT faces around 1958, to protect the phosphor … Meer weergeven • VIAS Science Cartoons A cranky view of an ion trap... • Paul trap Meer weergeven Some experimental work towards developing quantum computers use trapped ions. Units of quantum information called qubits are stored in stable electronic states of each ion, and quantum information can be processed and transferred … Meer weergeven • Laser cooling • Mass spectrometry • Quantum jump Meer weergeven Web7 apr. 2024 · Quantum Computing with Trapped Ions. We pursue proof-of-concept experiments in quantum information processing and quantum control with trapped ions. In addition to pushing current limits on traditional quantum gate-based architectures for quantum computing we explore alternative approaches to entanglement generation and …

Web21 jul. 2024 · Long qubit coherence lifetimes, 1-50s [ 4 ]; lifetime/gate speed implies c 100,000 cycles. Longer ‘memory’ qubit lifetimes up to 10mins [ 5] and recently 1 hour [ 6] have been reported. Extreme cryogenic cooling is not required; laser cooling is used instead. Ions form fundamentally identical qubits (though trap fabrication naturally ... Web9 okt. 2024 · Our apparatus is based on a segmented-blade ion trap enclosed in a 4 K cryostat, which enables us to routinely trap and hold over 100 171 Yb + ions for hours in a linear configuration, due to low background gas pressure from differential cryo-pumping. how does carplay work for iphone
