IBM Quantum System Two
IBM Quantum System Two is the first modular utility-scaled quantum computer system, unveiled by IBM on December 4, 2023. It is a successor to the IBM Quantum System One. It contains three IBM Quantum Heron processors, which can be scaled up due to its modularity, and later upgraded for newer QPU's, as it is fully upgradeable. For its maximum efficiency, it has to be cooled down to a temperature of a few hundredths of degrees above absolute zero (10-20 mK), using dilution technology. Current usage IBM has stated that their clients and partners are using their 100+ qubit In quantum computing, a qubit () or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device.

Yorktown Heights
Yorktown Heights is a census-designated place (CDP) in the town of Yorktown in Westchester County, New York, United States. The population was 1,781 at the 2010 census. History Yorktown Heights is in the town of Yorktown, New York, in northern Westchester County, 45 miles from New York City, with forty square miles of rolling hills, farmland, residential areas and light industry including the IBM Thomas J. Watson Research Center. First settled in 1683, Yorktown was of strategic importance during the American Revolution, with the Pines Bridge crossing of the Croton River guarded by the 1st Rhode Island Regiment, an integrated unit which included African Americans and Native Americans. Yorktown was incorporated in 1788 and named in commemoration of the Franco-American decisive victory at Yorktown, Virginia. The Yorktown Heights Railroad Station, which last had passenger service on the New York Central Railroad's Putnam Division in 1958, was added to the National Register of Histo ...

Quantum Computer
Quantum computing is a type of computation whose operations can harness the phenomena of quantum mechanics, such as superposition, interference, and entanglement. Devices that perform quantum computations are known as quantum computers. Though current quantum computers may be too small to outperform usual (classical) computers for practical applications, larger realizations are believed to be capable of solving certain computational problems, such as integer factorization (which underlies RSA encryption), substantially faster than classical computers. The study of quantum computing is a subfield of quantum information science. There are several models of quantum computation with the most widely used being quantum circuits. Other models include the quantum Turing machine, quantum annealing, and adiabatic quantum computation. Most models are based on the quantum bit, or " qubit", which is somewhat analogous to the bit in classical computation. A qubit can be in a 1 or 0 ...

IBM Quantum System One
IBM Quantum System One is the first circuit-based commercial quantum computer, introduced by IBM in January 2019. This integrated quantum computing system is housed in a 2.7x2.7x2.7 m airtight glass cube that maintains a controlled physical environment. The cylinder protruding from the ceiling in the center is a dilution refrigerator, containing a 20-qubit transmon quantum processor. It was tested for the first time in the summer of 2018, for two weeks, in Milan, Italy. IBM Quantum System One was developed by IBM Research, with assistance from the Map Project Office and Universal Design Studio. CERN, ExxonMobil, Fermilab, Argonne National Laboratory and Lawrence Berkeley National Laboratory are among the clients signed up to access the system remotely. From April 6 to May 31, 2019, the Boston Museum of Science hosted an exhibit featuring a replica of the IBM Quantum System One. On June 15, 2021, IBM deployed the first unit of Quantum System One in Germany at its headquarters i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBM Quantum Heron
IBM Heron is a 156-qubit tunable-coupler quantum processor created by IBM, originally unveiled during the IBM Quantum Summit 2023, which occurred on December 4, 2023, and is the highest performance quantum processor IBM has ever built. It is currently in use on the IBM Quantum System Two, unveiled during the same event. IBM claims that this processor eliminates cross-talk errors that emerged in their previous quantum processors, and that this processor is being made available for users via the cloud. The first version is reportedly 5 times faster than their previous best record set by the IBM Eagle IBM Eagle is a 127-qubit quantum processor. IBM claims that it can not be simulated by any classical computer. It is two times bigger than China's Jiuzhang 2.

Kelvin
The kelvin, symbol K, is the primary unit of temperature in the International System of Units (SI), used alongside its prefixed forms and the degree Celsius. It is named after the Belfast-born and University of Glasgow-based engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907). The Kelvin scale is an absolute thermodynamic temperature scale, meaning it uses absolute zero as its null (zero) point. Historically, the Kelvin scale was developed by shifting the starting point of the much-older Celsius scale down from the melting point of water to absolute zero, and its increments still closely approximate the historic definition of a degree Celsius, but since 2019 the scale has been defined by fixing the Boltzmann constant to be exactly . Hence, one kelvin is equal to a change in the thermodynamic temperature that results in a change of thermal energy by . The temperature in degree Celsius is now defined as the temperature in kelvins minus 273.15, meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dilution Refrigerator
A 3He/4He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK, with no moving parts in the low-temperature region. The cooling power is provided by the heat of mixing of the Helium-3 and Helium-4 isotopes. The dilution refrigerator was first proposed by Heinz London in the early 1950s, and was experimentally realized in 1964 in the Kamerlingh Onnes Laboratorium at Leiden University. The field of dilution refrigeration is reviewed by Zu et al. Theory of operation The refrigeration process uses a mixture of two isotopes of helium: helium-3 and helium-4. When cooled below approximately 870 millikelvins, the mixture undergoes spontaneous phase separation to form a 3He-rich phase (the concentrated phase) and a 3He-poor phase (the dilute phase). As shown in the phase diagram, at very low temperatures the concentrated phase is essentially pure 3He, while the dilute phase contains about 6.6% 3He and 93.4% 4He. The ...

Qubit
In quantum computing, a qubit () or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples include the spin of the electron in which the two levels can be taken as spin up and spin down; or the polarization of a single photon in which the two states can be taken to be the vertical polarization and the horizontal polarization. In a classical system, a bit would have to be in one state or the other. However, quantum mechanics allows the qubit to be in a coherent superposition of both states simultaneously, a property that is fundamental to quantum mechanics and quantum computing. Etymology The coining of the term ''qubit'' is attributed to Benjamin Schumacher. In the acknowledgments of his 1995 paper, Schumacher states that the term ...
