As I said, only noiseless simulations, half assed annealers and noisy intermediate scale computers. A functional general quantum computer does not exists. All the "applications" right now are research.
And even if said computer existed, the only algorithm with demonstrable quantum supremacy is Shor (if you want to poke let's also say Grover, but argument unchanged), which could break cryptographic problems (e.g. Satoshi's BTC) but does not have clear commercial applications. Besides those, there isn't a demonstrable edge that a functional quantum computer would offer, if there was the papers should be able to show the algorithmic efficiency.
And **TODAY** you are going to pay $2 billion for QUBT, the SPAC former soda company with less quarterly revenue than my household income, whose HQ looks like a New Jersey public housing project...
They are not low price and there is no general quantum computer no matter how much people want it to be so, or how much they are willing to pay for it.

Him and his wife is referred to as "we" it looks like. Stock is up about 100% since then. It was higher but has gone down a bit, but still up a lot compared to pre announcement price. A lot of people calling it pump and dump because of it was announced the same day as he lost a lot on CAPR. However, it hasn´t dumped. Just consolidated.

Q/C has exclusive rights to a laser-patent from the company LightSolver.
Shkreli is trying to hire people from the Microsoft Optical team.
He announced he was going to be in SF and DC this week.

To put things in perspective, Ticker QUBT (Quantum computing INC)
Sold ink cartridges in 2001
Pivoted to beverage distribution in 2007
Was involved in a shell company merger in 2018 and changed its name to Quantum Computing Inc from Innovative Beverage Group Holdings, Inc.
Market cap 2023 = 68 million dollars
Market today = 2.8 billion dollars
Quantum Computing Inc does not make quantum computers...
So even if you have little faith in the technology, the stocks have had insane gains.

I've been selling some calls against RGTI; holding off (so far) on IONQ, QBTS, and QUBT.
RGTI was low delta (\~10) at initiation.
Dicey situation.

Many QC stocks got crushed recently — and now **low-price** names like **RGTI** and **QUBT** are looking interesting again for **high vol** setups. I run everything through to visualize payoff + Greeks, potential P/L, and assignment risk. (Usually \~30–60 DTE, but it depends.)
What do you think — anyone else selling vol here?

Quantum companies producing hardware is not all that different from Nvda manufacturing hardware and software “the tools for the job” to customers whose job it is to monetize them. That said, that is where the comparison starts and ends. Like others said, the catalyst hasn’t come yet and these companies are all still very speculative. Here are some notes from my own tracking of them.
The most stable choices atm are Amzn and IBM due to their focus on quantum and their blue chip statuses. These are the only 2 of the entire category that have solid Sales, Margin, Revenue (SMR) stats.
IonQ has Amazon investment and is a major supplier of hardware for them.
If the risky companies, all of them are negative free cash flow, and QUBT has the lowest PB ratio, commonly used instead of PE for companies that aren’t yet profitable.
IONQ, QBTS, and RGTI appear to have the strongest market support based on watching them almost daily for the past 6 months. IONQ and QBTS both show substantial sales and revenue growth, 200%+.
RGTI still has terrible financials but retail momentum despite having declining sales and revenue growth, as well as a PS ratio 3x higher than QBTS. It does have the 2nd lowest PB ratio of the group tho.
LAES has a promising potential moat but is still stabilizing in its IPO cycle and admittedly on the top half of its range which is bullish. On weekly chart, it is holding 50-SMA support, so I’d watch how it behaves there as a good entry with tight stop loss if it fails support.
QTUM is an ETF where you can get exposure but it is definitely higher valuation and its top holdings include only RGTI from this list and then other chip and semiconductor companies like AMD and INTC.

I was looking for a possible lower high on the weekly chart on the quantum names. For quantum I usually watch IONQ, RGTI, QBTS, and QUBT. From a liquidity standpoint I usually prefer IONQ or RGTI. If you look at the 1m chart at 9:35AM EST RGTI was weaker than IONQ and was almost back at the low of the day after the pop off the bell. That's what had me choose it.
