1610-1620: From the Late Latin quantum, noun use of the neuter form of the Classical Latin quantus (how much). Quantum was imported from Latin to physics by German
theoretical physicist Max Planck (1858–1947) to describe the concept of the "minimum
amount of a quantity which can exist".
Quantum theory is from 1912 and quantum mechanics from 1922, the latter
much associated with German theoretical physicist Werner Heisenberg (1901-1976)
who in 1927 deduced his "uncertainty principle", declaring an electron
may have a determinate position, or a determinate velocity, but not both. In physics, the term "quantum jump" (the abrupt
transition from one stationary state to another) came into use in 1954 while "quantum
leap" (sudden large advance) dates from 1963 and in figurative use (by
non-physicists) describes some drastic change or radical advance in some aspect
of something (and is thus often synonymous with that other favorite of
post-modernists, the "paradigm shift". There
are pedants (and one suspects few of them actually comprehend quantum theory) who
insist “quantum leap” in the sense of “sudden & big is wrong but it’s just
part of the evolution of English in its usual democratic way. Quantum is a noun and adjective; the noun plural
is quantums or quanta.

IBM quantum computer.In an announcement little noted outside
the nerd community, in late 2021 IBM introduced the CLOPS (Circuit Layer Operations per Second) performance
standard for quantum computing. As a
measuring metric, CLOPS corresponds to the number of quantum circuits a QPU (quantum
processing unit) can execute per unit of time, the innovation compared
with previous standards such as FLOPS (Floating
Point Operations per Second) and its variations (ranging from kiloFLOPS
(KFlops:103) to yottaFLOPS (YFlops: 1024)), in that it
expresses not only the actual speed at which the workload is processed and
successfully completed but also adjusts to account for the latency of the
interaction between the quantum and classical computing realms. It must be noted that to date, the pure quantum computer
has existed only in theory and that functions now executed in the quantum space
involve an interaction, being mediated via a classical binary computer which translates
workloads into a QPU-compatible format, retrieves the workload's results and
presents them in an understandable form. CLOPS thus accounts for not only the interval
of time that the workload is actually being processed at the qubit (quantum
bit) level, but also the time it takes for the system to translate and transfer
information across both components. If written down, a yottaFLOP (1024) is a number with 24 trailing zeros (1,000,000,000,000,000,000,000,000) and that's one septillion calculations per second. It now sounds a big number and by most standards it certainly is; probably even trillionaire Elon Musk (b 1971) would be impressed (a trillion (1012) has twelve zeros (1,000,000,000,000). However, advances in computing (quantum as well as bio-computers that are a blend of manufactured hardware good at many things and a biological brain better at others) will continue and beyond yotta awaits ronna (1027) and quetta (1030). Numbers are infinite so if the FLOPs count ends up as something now inconceivably large, all that will be required is another tag in the lineage that began modestly enough with kilo (103) & mega (106).
Dating back decades, IBM has published many standards
which the industry has adopted ranging from specifications for memory addressing
to video displays (the once-famous CGA (Color Graphics Adaptor), EGA (Enhanced Graphics Adaptor), VGA (Video Graphics Array), XGA (eXtended Graphics Array)) and had for some time
discussed the need for a harmonized standard for quantum computing. Until CLOPS was announced, the measures had
usually been expressed in terms of two of quantum’s three planes: (1) scale
which pertains to the number of qubits present in any given system and (2) quality
which refers to the proportion of qubits that can perform usable work expressed
via quantum volume. What CLOPS does is provide
a formula to express a measure of (3) speed. IBM has published CLOPS results for some of its quantum
computing systems using machines constructed with between five and 64 qubits
and it was interesting to note all had a similar quantum volume score, their
actual speed (expressed in CLOPS) varied between 753 and 1419 layers per second;
as IBM predicted, it was latency which accounted for the difference. Noting that, IBM also published results from
their Qiskit (Quantum Information Software Kit for Quantum
Computation) project which focuses on reducing the latency in the quantum-classic
computing translation layer seriously via closer physical proximity between the
objects, some experiments reducing run-time cycles from 45 days to nine hours. The company expects CLOPS to be the defined measure
of quantum computing in its present form as FLOPs and its variations were to super-computing.

Lindsay Lohan: Manifestation, Fame, and the Alchemy of Identity (2025) by The Universe Unveiled. A slim volume of 70 pages

of the language of quantum mechanics.
The term “quantum theatre” does not come
from theoretical physics but is, a little opportunistically, a figurative form. It’s used to refer to situations,
environments or performances where there’s some felling of “instability” in
reality, a perception multiple contradictory outcomes appear to be happening at
the same time, one implication being the observer being able to “change reality”
merely by the act of watching. What the
term adapts from quantum mechanics are the concepts superposition, entanglement
and the observer effect, applying them to aspects of human behaviour: politics,
art or anything performative. So, while
opportunistic, the re-purposing is compelling because “superposition” is best
understood as the “illusion of choice” and that’s used to describe a situation in
which all possibilities in theory exist but, at the point when a decision is
made, the illusion collapses into a single reality and that can be satisfying,
disappointing, chaotic, disastrous or any of the possibilities. In a number of interviews, Ms Lohan has
reflected on the consequences of those “moments of decision”.

The “observer effect” is especially
relevant. The essence of reality
television, social media and such, it describes the phenomenon of the behaviour
of individuals changing purely because they know they are being watched. The actions of living things are different
from those of inanimate objects; a sofa does not respond to being looked at but
people sitting on it might be so influenced, making a “performance” fundamentally
artificial compared with what would have happened had they not become aware of
being viewed. The now well-documented “perception-driven
reality” (an environment where facts matter less than how the audience
perceives them) is what underpins the success of social media, the mechanisms
explained decades earlier in cognitive theory, the very “theatre” shifting
shape based on a viewer's bias. Most
intriguing of course is connected chaos (entanglement). In the figurative use, that’s a narrative or
situation in which two unrelated events or people are deeply linked, an act in
one place instantly changing the dynamics in another. As an aspect of the understanding
of the “performative”, the possibilities of that have been explored in art,
stage plays or interactive exhibits that allow the audience's choices or
presence physically to change the story or ending and the advances in AI
(artificial intelligence) hint this may the future of on-screen entertainment,
the audience becoming part of the cast and interacting with the
characters. A concept long possible in
the pages of fictional texts, it may soon be coming to a screen near you.

New
York City, 9/11.
German photographer Thomas Hoepker (1936–2024) was for decades
attached to the Magnum Agency and on 11 September, 2001, while in Williamsburg,
Brooklyn, he took what became a controversial photograph of the terrorist
attacks on the twin towers of the WTC (World Trade Center). Herr Hoepker, for obvious reasons, was
attempting to get close to southern Manhattan but he parked his car when he saw
what struck him as a “strange scene” in the aftermath of the attack:
A group of young people lounging on a bench as a cloud of black smoke drifted
into the blue sky behind them. Without
the knowledge or consent of the subjects, He took the image from a distance, later
explaining: “If
you started a conversation or asked permission, you would change any authentic
situation in an instant.” Such
was an old documentarian’s understanding of the “observer effect” and he also
appreciated the effect the juxtaposition might have if published at the time;
not until a retrospective of his work was exhibited in 2006 was the photograph
publicly displayed. As he had expected,
much comment suggested there was “callousness” being shown but two of the
subjects subsequently responding in a letter to a magazine: “We were in a
profound state of shock and disbelief. Had
Hoepker walked 50 feet over to introduce himself, he would have discovered a
bunch of New Yorkers in the middle of an animated discussion about what had
just happened.” That would
have been the “observer effect”.
