Quantum cryptography and Post-Quantum cryptographyHello guys
today i want to explain Quantum cryptography and Post-quantum cryptography
and how they can affect blockchain security and whats the solution.
lets start with a brief explanation of cryptography:
Cryptography is the process of encrypting data, or converting plain text into scrambled text
so that only someone who has the right “key” can read it.
NOW what is quantum cryptography?
Quantum cryptography simply uses the principles of quantum mechanics
to encrypt data and transmit it in a way that cannot be hacked.
and what is Post-Quantum cryptography?
Post-quantum cryptography refers to cryptographic algorithms (usually public-key algorithms)
that are thought to be secure against an attack by a quantum computer.
These complex mathematical equations take traditional computers months or even years to break.
However, quantum computers running Shor’s algorithm will be able to break math-based systems in moments.
How Quantum Cryptography Works?
Quantum cryptography, or quantum key distribution (QKD), uses a series of photons (light particles)
to transmit data from one location to another over a fiber optic cable.
By comparing measurements of the properties of a fraction of these photons,
the two endpoints can determine what the key is and if it is safe to use.
The sender transmits photons through a filter (or polarizer) which randomly gives them one of four possible polarizations
and bit designations: Vertical (One bit), Horizontal (Zero bit), 45 degree right (One bit), or 45 degree left (Zero bit).
The photons travel to a receiver, which uses two beam splitters (horizontal/vertical and diagonal) to “read” the polarization of each photon.
The receiver does not know which beam splitter to use for each photon and has to guess which one to use.
Once the stream of photons has been sent, the receiver tells the sender which beam splitter
was used for each of the photons in the sequence they were sent, and the sender compares that information with the sequence of polarizers used to send the key.
The photons that were read using the wrong beam splitter are discarded, and the resulting sequence of bits becomes the key.
If the photon is read or copied in any way by an eavesdropper, the photon’s state will change.
The change will be detected by the endpoints. In other words, this means you cannot read the photon and forward it on or make a copy of it without being detected.
The Solution We Need Now for Tomorrow!
The need for unbreakable encryption is staring us in the face.
With the development of quantum computers looming on the horizon, the integrity of encrypted data is at risk now.
Fortunately, quantum cryptography, through QKD, offers the solution we need to safeguard our information well into the future – all based on the complex principles of quantum mechanics.
In January 2022 a team at Sussex University spin-out company Universal Quantum published research on transit attacks
which calculated that it would require a quantum computer with a 1.9 billion qubit-capacity to break Bitcoin’s encryption in the required ten-minute window
(this is the time taken for a Bitcoin to be mined). Even at 317 million qubits it would take an hour and 13 million qubits for a day.
For context, IBM’s superconducting quantum computer currently has a 127-qubit processor.

Special to Quantum ComputingIt's often said the people who made money during the Gold Rush were pick makers and Lewis Jeans Co. In the digital world, leaders in computing power are at the forefront of the biotech, robotics and AI revolution that we have embarked on. Grab your seat... "mutability" is a powerful skill to have. Understanding the environment and adapting to the ever changing landscape has never been more important. Let's talk about those SPACs Never been a fan until just last week more as a co-research project I'm working on for security.
Let's focus on one that was announced last Feb 2022 and is heading to a Special Shareholder Vote tomorrow. "D-Wave Systems, a provider of quantum computing systems, software, and services, said Tuesday that it has agreed to merge with special purpose acquisition company DPCM Capital (XPOA) to become a publicly-traded entity."
There is a special shareholder meeting for holders of this SPAC to readjust to the changing times. That event will happen tomorrow August 2nd 2022. If you missed it, check with IR and SEC public filings at edgar.sec.gov As a US regulated company, it should all be there. D-Wave in Canada is currently private and apparently firing on all cylinders from informal observations.
Canada filings would be done within the appropriate Authority & Regulator for that Jurisdiction. Check with a financial advisor. I'm just an observer on a keyboard that likes to look at charts, keep my nose clean and study the markets to find possible gems in the muck of "stuff".
D-Wave Systems is a great candidate for a SPAC reverse-IPO thing. Let's hope the Regulators on both sides of the border work together to make sure all eyes are on this one.
Note: This was the last update with summary from Feb 2022:
Update: D-Wave to Go Public via Merger with SPAC DPCM Capital; DPCM Shares Rise
Feb 8, 202208:47
(Updates with stock move in the headline and last paragraph.)
D-Wave Systems, a provider of quantum computing systems, software, and services, said Tuesday that it has agreed to merge with special purpose acquisition company DPCM Capital (XPOA) to become a publicly-traded entity.
Upon closing of the deal, shares of D-Wave Quantum Inc., a newly formed parent company of D-Wave and DPCM Capital, will start trading on the NYSE under the symbol QBTS.
The transaction values D-Wave at an equity value of roughly $1.2 billion. D-Wave plans to use proceeds of $340 million to further accelerate its delivery of in-production quantum applications for blue-chip customers and to build on over 200 US patents that it has been granted.
After the closing of the deal, the combined entity will continue to operate from D-Wave's R&D and head office location in British Columbia, Canada.
The Analysis:
TA As of August 1st 2022. Tradingview TA www.tradingview.com (note: XPOA symbol to change to QBTS apparently?)
Summary: SELL 14,7,5 (watch last number increase as Yes vote gets confirmed, the current hypothesis)
Oscillators BUY 1,6,4 (mostly neutral at 6 but 4 should be increasing)
Moving Averages STRONG SELL 13,1,1 (MA-only based short sellers/algos/traders want to sell. This could be a formidable short squeeze potential in vote is large, or shorts could be predicting this is garbage).
Fundamentals
Everything depends on the vote tomorrow. Based on all information findable in Public (via SEC Edgars and other official sources). This is a Watch or Casino Bet pending vote. Tomorrow will confirm a Bullish Run or an abysmal US SPAC failure. Dog Food Fund Candidate "pre-IPO" "smelly SPAC" XPOA -> NYSE QBTS Quantum Computing "junior" that is a leader in its North American space. Place your bet, trade or investment .

qtum swing ~qtum looks to be in a very nice bull channel;
so long as it stays inside of it, i do think we could move back to the top of it.
shave some profit off at the midline if anything, closer to $17; also move stops to breakeven \ in profit once it begins to move.
failure to hold the bull channel will result in a deeper dip.
stop loss on the other side of the bull channel.
take profit 1: 17
take profit 2: 21
$ARQQ: Quantum Leap?Risky play given the deflationary environment and recent ARKK weakness but I fully believe some stocks I feel are too risky not to be exposed to. Apart from price action and personal conviction, I am waiting to see if a potential $BUG (cybersecurity ETF) breakout could help $ARQQ as well
$DMYI -> $IONQQuantum computing space leader. Nice combination of:
- good quality company with 0 revenue and Multi Billion Market potential.
- options open interest + low float (exponential delta increase + gamma squeeze as many like)
- recent comparable companies did run from 10 to 40s ($ARQQ)
QTUMUSD - Breakout SoonHello,
Check out QTUM for the next Bull Cycle, it can reach good prices then.
Thank you,

QTUM $155.4 (2244%) at The End of July 2021We can see on the elliott wave ABCDE there is the same pattern as the previous cycle. In waves A to B (High to Low) it takes about 12 days. From the lowest point to the next highest point (B to C) it takes about 73 days. Then from the highest point to the next low (C to D) takes 16 days. Then the next biggest wave will start, the journey from the lowest point C to the highest point D will last for 69 days. It will end at the end of July with an increase of more than 2244% or the equivalent of $155.4.
There is something unique here, the key is number 4.
Every highest increase to the highest x4
Previous uptrend phase to the next uptrend -4d
The previous downtrend phase to the next downtrend +4d
The number 4 for QTUM (Quantum) is very magical, just like the Four quantum number in physics,
Principal quantum number (n)
Azimuthal quantum number (ℓ)
Magnetic quantum number (mℓ)
Spin quantum number (s)
Don't miss the opportunity, QTUM is on its way to new ATH.
Qtum going straight into R3 YearlySuper clean setup. Qtum had one of the largest capitulations vs BTC. Now reclaimed support, above the Yearly P, retested R3 monthly + Volume Profile PoC and it looks very nice and steady. Old coins have been doing well and their trend is very clear. IOTA, ZEN, NEO, EOS, BCH, LTC, DOGE, SC and that could continue for some time. Lots of layer 1 protocols, most are useless but it's their time.
